Bonanza is a mining-themed online slot created by Big Time Gaming. Released in 2016, it became the first widely recognized title to demonstrate the full potential of the developer’s Megaways mechanic, which later influenced a large part of the modern online slot market. Big Time Gaming describes Bonanza as the original Megaways game, offering up to 117,649 possible ways to win on a single spin.
Canadian players can find Bonanza in the game catalogue at Betty Casino, subject to account location and current platform availability. The dedicated Betty game page allows eligible users to open the slot and review the version provided through the casino.
Bonanza differs from a conventional fixed-payline slot. Its reel height changes from spin to spin, so the number of active winning combinations is not constant. One round may begin with a relatively small number of ways to win, while another can use the maximum reel configuration and provide 117,649 possible combinations.
The game combines this variable reel system with cascading symbols, Wild substitutions and a Free Spins feature containing an increasing multiplier. Although the basic controls are accessible, the mathematical structure is more dynamic than that of a traditional slot with a fixed number of rows and paylines.
Bonanza Slot Overview
The game is set inside a gold mine surrounded by railway tracks, rock formations, mining equipment and valuable gemstones. The background follows a rugged western landscape, while the reels are positioned near the entrance to the mine.
Bonanza uses six main reels. Each reel can display between two and seven symbols, creating a different layout on every spin. A separate horizontal reel appears above the main grid and contains four additional symbol positions.
The main characteristics of Bonanza include:
- Developer: Big Time Gaming;
- Release period: 2016;
- Theme: gold mining and gemstones;
- Main reels: six;
- Additional reel: one horizontal four-position reel;
- Reel height: between two and seven symbols per main reel;
- Maximum winning ways: 117,649;
- Payline system: Megaways;
- Main feature: Cascading Reels;
- Bonus feature: Free Spins;
- Bonus multiplier: increases after qualifying cascades;
- Volatility: high;
- Published theoretical RTP: approximately 96%;
- Published maximum win: up to 26,000 times the stake;
- Supported format: HTML5 desktop and mobile play.
The official Big Time Gaming presentation lists Bonanza with a 96.11% RTP and maximum potential of 26,000 times the bet. The exact configuration available at Betty Casino should still be checked inside the game information panel, because casinos and jurisdictions may offer different certified versions.

The Mining Theme and Visual Design
Bonanza presents a traditional mining environment rather than a highly animated fantasy setting. Wooden supports, railway tracks and mountain scenery establish the location, while colourful gemstones provide the main visual focus on the reels.
The reel symbols include diamonds and other stones in several colours. Mining equipment appears among the higher-value icons, while letters and card ranks form the lower-value group.
The visual design is structured around clarity. Since reel heights can change on every spin and symbols disappear during cascades, the interface needs to show several mathematical changes without becoming difficult to follow.
The soundtrack uses western and mining-inspired effects. Reel movements, gemstone explosions and bonus notifications make it easier to identify winning cascades and special-symbol appearances. Sound can normally be adjusted or disabled through the game controls.
How the Megaways Mechanic Works
Megaways replaces fixed paylines with a variable ways-to-win system. Every main reel receives a random height before the symbols appear. Because each reel can show a different number of symbols, the total number of possible combinations changes on every paid spin and cascade.
The number of ways is calculated by multiplying the visible symbol positions on the six main reels.
For example, a reel configuration of:
- 3 symbols on reel one;
- 4 symbols on reel two;
- 5 symbols on reel three;
- 4 symbols on reel four;
- 6 symbols on reel five;
- 3 symbols on reel six;
would create:
3 × 4 × 5 × 4 × 6 × 3 = 4,320 ways to win.
The maximum configuration uses seven symbols on all six main reels:
7 × 7 × 7 × 7 × 7 × 7 = 117,649 ways.
The horizontal reel above the main grid does not directly increase the Megaways calculation. Instead, its symbols can match icons on the main reels and participate in the game’s reaction mechanics.
A higher number of active ways creates more possible symbol combinations, but it does not guarantee that a winning combination will appear. Every spin is generated independently by the game software.

How Winning Combinations Are Formed
Bonanza does not require symbols to land on a predefined line. A standard win is formed when matching symbols appear on consecutive reels beginning with the first reel on the left.
The symbols do not need to occupy the same row. Any qualifying symbol on one reel can connect with matching symbols on the next adjacent reel.
Most regular wins require:
- At least three matching symbols;
- Matching symbols on consecutive reels;
- A combination beginning on the first reel;
- Enough matching icons to satisfy the paytable requirements.
Suppose a gemstone appears twice on the first reel, three times on the second reel and twice on the third reel. The game can calculate multiple combinations from those matching positions:
2 × 3 × 2 = 12 winning ways.
If the same symbol also appears on the fourth reel, the total number of combinations can increase further.
Several different symbols may produce qualifying combinations during the same spin. Each result is calculated according to the game’s paytable and then added to the total round payout.
Cascading Reels Explained
Cascading Reels are one of the central mechanics in Bonanza. After a winning combination is calculated, the symbols involved in that win disappear from the grid.
The remaining symbols move downward, while new icons enter from above to fill the empty positions. This creates another opportunity to form a winning combination without requiring an additional paid spin.
The process follows this sequence:
- The reels stop and the game evaluates all active Megaways combinations;
- Qualifying symbol groups produce a payout;
- Symbols involved in winning combinations are removed;
- Remaining symbols fall into the empty spaces;
- New symbols enter the grid;
- The game evaluates the updated layout;
- Further wins trigger another cascade;
- Cascades continue until no new qualifying win appears.
A single paid spin can therefore produce several consecutive payouts. The total value of all cascades is combined and credited when the complete reaction sequence ends.
Cascading wins do not guarantee that every subsequent reaction will be successful. A sequence may stop after one payout, or several reactions may occur before no further winning combination remains.
The Horizontal Reel and Dual Reaction System
Bonanza includes a horizontal reel above the six main reels. It displays four symbols and plays an important role in the game’s special reaction mechanic.
When a symbol on the horizontal reel matches a winning symbol on the main grid, it may also be removed during the cascade. New symbols then enter both the main reel area and the upper reel.
This two-directional movement is sometimes described as a dual-reaction system because new symbols can arrive vertically on the main reels and horizontally on the top reel. Big Time Gaming identifies this combination of Megaways and reaction mechanics as one of the defining elements of Bonanza.
The upper reel can also contain special symbols involved in the Free Spins trigger. Players should review the paytable to understand exactly how each horizontal-reel symbol functions in the available Betty Casino version.
Bonanza Symbols and Paytable
The regular paytable is divided into premium mining symbols and lower-value card-rank icons.
Premium Symbols
The premium symbols are represented by colourful gemstones. They generally offer stronger payouts than the card ranks when enough matching icons appear across consecutive reels.
The exact value of a gemstone combination depends on:
- The type of gemstone;
- The number of consecutive reels involved;
- The number of matching symbols on each reel;
- The selected stake;
- Whether Wild symbols complete the combination.
Because Bonanza uses winning ways rather than paylines, several copies of the same symbol on one reel can contribute to multiple combinations at the same time.
Low-Value Symbols
The lower-value icons are stylized card ranks:
- Ace;
- King;
- Queen;
- Jack;
- Ten;
- Nine.
These symbols normally appear more frequently but provide smaller individual payouts. Multiple card-rank combinations can still produce a meaningful total when they involve several reels or occur across repeated cascades.
Wild Symbol
The Wild is represented by mining dynamite. It can substitute for most regular symbols and help complete winning combinations.
The Wild does not generally replace special bonus-triggering symbols. Its exact substitution rules should be checked in the in-game paytable.
Wilds can become especially useful when several copies of a premium symbol appear across adjacent reels but one position needed to complete the combination contains a different regular icon.
Scatter Symbols
The letters G, O, L and D act as special Scatter symbols. They are connected to the Free Spins feature and normally appear on specific reel positions, including the horizontal reel.
The complete word “GOLD” must be formed to trigger the bonus round. Unlike regular winning combinations, these letters follow their own placement requirements rather than the standard left-to-right Megaways calculation.
The number and position of qualifying letters should be confirmed in the game rules displayed at Betty Casino.
Bonanza RTP Explained
RTP means Return to Player. It represents the theoretical percentage of total stakes that a game is designed to return over a very large number of simulated or real rounds.
The official Big Time Gaming game page presents Bonanza with an RTP of 96.11%. This means that, in the specified mathematical configuration, the slot is designed to return an average of CA$96.11 from every CA$100 wagered over extensive long-term play. It does not mean that a player depositing CA$100 will receive CA$96.11 back during one session.
Short-term results can differ substantially from the theoretical percentage. One session may end above the original balance, while another may produce a full loss without activating the main feature.
Players should check the RTP inside the Betty Casino version before placing a wager. The number shown in the live game information menu is the relevant figure for that particular configuration.
High Volatility and Balance Fluctuations
Bonanza is generally classified as a high-volatility slot. High volatility indicates that results can be uneven, with longer periods of limited returns and occasional larger winning sequences.
This structure is influenced by:
- The variable number of active winning ways;
- The cascading reel system;
- The Free Spins feature;
- The increasing bonus multiplier;
- The game’s maximum payout potential;
- The possibility of several reactions from one initial spin.
High volatility does not mean that a large win is due after a losing sequence. Every result is generated independently, and previous spins do not create a mathematical obligation for the game to produce a payout.
A higher bet also does not improve the probability of triggering Free Spins or creating a winning combination. It only changes the monetary value of the amount risked and any resulting payout.
RTP and Volatility Are Different Metrics
Long-term theoretical return and short-term balance movement describe separate elements of the game model.
Return to Player
A long-term theoretical percentage calculated across extensive gameplay, not a guaranteed return for one session.
Volatility
Results may include extended periods of limited returns and occasional stronger cascade or bonus sequences.
What high volatility can mean
A balance can change quickly when the stake represents a large portion of the available bankroll. Maximum Megaways layouts, repeated cascades and Free Spins remain random.
Maximum Win Potential
The official Big Time Gaming presentation lists a maximum win of up to 26,000 times the stake for Bonanza.
The monetary value depends on the selected bet:
- A 26,000x payout at CA$0.20 would equal CA$5,200;
- A 26,000x payout at CA$0.50 would equal CA$13,000;
- A 26,000x payout at CA$1 would equal CA$26,000.
These examples only illustrate multiplication and do not indicate how likely the maximum result is. Maximum wins are rare and may also be subject to platform-specific payout limits.
Before playing, users should review:
- The maximum win shown in the paytable;
- Betty Casino’s maximum payout rules;
- Any daily or transaction-related withdrawal limits;
- Bonus restrictions that may cap promotional winnings;
- The maximum stake permitted while using bonus funds.
Bonanza on Mobile Devices
Bonanza uses HTML5 technology and is designed to run on compatible smartphones, tablets and desktop browsers. No separate desktop software is normally required.
The mobile version retains the principal mechanics:
- Six variable-height reels;
- The horizontal reel;
- Up to 117,649 winning ways;
- Cascading wins;
- Wild substitutions;
- GOLD Scatter symbols;
- Free Spins;
- Increasing bonus multipliers.
On a smartphone, the interface automatically scales to fit the available display. Landscape orientation may provide a wider view of the reel structure, while portrait mode can be more convenient for one-handed navigation.
A stable internet connection is recommended because each spin and cascade is processed through the game server. If the connection is interrupted during a round, players should reopen the game and check the balance and transaction history before repeating the wager.
Demo Play and Real-Money Mode
A demo version may be available depending on Betty Casino’s settings and the player’s location. Demo mode uses virtual credits and allows users to explore the mechanics without risking deposited funds.
It can be useful for learning:
- How the reel heights change;
- How winning ways are calculated;
- How cascading symbols work;
- Where GOLD letters appear;
- How the horizontal reel reacts;
- How the paytable displays symbol values;
- How the betting controls operate.
Demo results cannot predict real-money outcomes. Both modes use the same general game rules, but virtual credits remove the financial consequences of losing spins.
Real-money access requires an eligible account, sufficient balance and compliance with the applicable provincial and platform requirements. Players should use only discretionary funds and avoid treating Bonanza as a reliable source of income.
Bonanza Free Spins Feature
The Free Spins feature is the main bonus round in Bonanza and the mechanic that gives the slot much of its high-volatility character. It is activated by landing the four special letter symbols required to spell the word “GOLD”.
The letters appear in designated positions across the main and horizontal reels. Unlike regular gemstone combinations, they do not need to create a standard left-to-right Megaways win. The feature begins once all four required letters are visible within the same completed reel result.
A standard trigger awards 12 Free Spins. During the bonus round, every successful cascade increases the active multiplier by one. The multiplier does not reset between individual Free Spins, allowing it to grow throughout the entire feature.
The exact bonus configuration available at Betty Casino should always be verified through the game’s information menu. Certified versions may differ in their RTP setting, stake limits or maximum payout conditions.
How the GOLD Symbols Trigger Free Spins
The four bonus symbols display the letters:
- G;
- O;
- L;
- D.
Each letter normally appears in a specific part of the reel structure. Together, they form the complete GOLD sequence required to activate Free Spins.
The letters do not function like ordinary paying symbols. They are not evaluated through the variable Megaways calculation and do not need to appear on consecutive reels in the same way as gemstones or card ranks.
When the complete word appears, the current base-game cascade sequence is resolved before the bonus begins. The game then transfers the player to the Free Spins screen and displays the number of awarded rounds.
A partial combination does not activate the bonus. Landing G, O and L without the D symbol, for example, produces no Free Spins unless the missing letter appears through a qualifying reaction permitted by the game rules.
Increasing Multiplier During Free Spins
The increasing multiplier is the defining feature of the Bonanza bonus round.
Free Spins begin with a 1x multiplier. Every cascade that produces a qualifying win increases the multiplier by one before the next reaction is evaluated.
A typical sequence may operate as follows:
- A Free Spin begins with the multiplier at 1x;
- A winning combination forms;
- The symbols involved are removed;
- The first cascade increases the multiplier to 2x;
- New symbols enter the reels;
- Another win increases the multiplier to 3x;
- Reactions continue until no additional win appears;
- The next Free Spin begins with the accumulated multiplier preserved.
The multiplier remains active for the rest of the bonus. It does not normally return to 1x after an unsuccessful Free Spin.
This creates the possibility that later spins will use a substantially stronger multiplier than the opening rounds. However, multiplier growth depends entirely on successful cascades. A feature with few winning reactions may finish with only a modest increase.
Free Spins Multiplier Progression
Winning cascades increase the multiplier, which remains active across the bonus feature.
Multiplier rules
The multiplier grows only after qualifying bonus cascades. It does not guarantee that later Free Spins will create a winning combination or recover the feature’s triggering cost.
Example of a Multiplied Cascade Sequence
Suppose the active multiplier has reached 4x and a new Free Spin produces a gemstone combination worth CA$5 before multiplication.
The initial win would be calculated as:
CA$5 × 4 = CA$20.
After the symbols disappear, the multiplier increases to 5x. If the next cascade produces a base payout of CA$3, the result would be:
CA$3 × 5 = CA$15.
If another reaction follows, the multiplier rises again before that new cascade is evaluated.
The total returned by the complete Free Spin would include all multiplied cascade payouts:
- First result: CA$20;
- Second result: CA$15;
- Additional reactions: added separately;
- Total Free Spin payout: combined after the sequence ends.
This example is only a mathematical illustration. It does not represent an expected bonus result or guarantee that several cascades will occur.
Bonus Buy Availability
Some modern slots allow players to purchase direct access to a bonus feature. The original Bonanza game does not universally include a Bonus Buy function, and its availability may depend on the specific software version, jurisdiction and Betty Casino platform settings.
Where any direct feature-access option is offered, players should review:
- The complete purchase price;
- The number of included Free Spins;
- The RTP assigned to the purchased feature;
- Maximum payout conditions;
- Promotional-balance restrictions;
- Applicable provincial rules;
- Whether the feature purchase counts toward wagering requirements.
A bonus purchase only provides access to the feature. It does not guarantee that the resulting payout will exceed the purchase cost.
Bonanza and Betty Casino Bonuses
Betty Casino may offer deposit bonuses, promotional credits, Free Spins or other rewards to eligible Canadian players. Bonanza may contribute differently to wagering requirements depending on the terms of the active promotion.
Before using bonus funds, players should check:
- Whether Bonanza is included in the eligible game list;
- The wagering contribution percentage;
- The maximum permitted bet;
- The minimum deposit requirement;
- The wagering deadline;
- Restricted payment methods;
- Maximum convertible or withdrawable winnings;
- Provincial eligibility conditions.
A wagering requirement determines how much qualifying play must be completed before bonus-related funds can become withdrawable.
For example, a CA$100 bonus subject to a 30x bonus-only requirement would require CA$3,000 in eligible wagers:
CA$100 × 30 = CA$3,000.
If the requirement applies to both the deposit and bonus, the total required wagering amount would be higher.
Players should not assume that every slot contributes 100%. Some promotions exclude high-volatility games, feature purchases or selected providers.
Withdrawals and Account Verification
Withdrawals usually require an eligible balance, completed wagering conditions and successful identity verification.
Betty Casino may request documents confirming:
- Identity;
- Age;
- Residential address;
- Ownership of a payment method;
- Source of funds;
- Transaction activity;
- Changes to personal information.
Common documents may include a government-issued photo ID, recent proof of address, bank statement or payment ownership confirmation.
Uploaded files should be:
- Clear and readable;
- Complete;
- Unedited;
- Valid and current;
- Consistent with the account information;
- Submitted through the designated secure channel.
Withdrawal processing can include two separate stages: the casino’s internal review and the payment provider’s transfer time. A withdrawal marked as processed may therefore still require additional time to appear in a bank account or digital wallet.
Canadian Provincial Availability
Online casino availability in Canada depends on provincial law and the operator’s authorization to serve players in a particular location.
Players should not assume that access is identical across all provinces and territories. Account registration, game availability, payment options and promotional conditions may vary according to the user’s physical location.
Location verification may rely on:
- Registered residential address;
- IP address;
- Device location services;
- Payment information;
- Identity documents;
- Geolocation software.
VPNs, proxies or other tools that conceal the actual location can interfere with account access and may breach platform rules.
Ontario uses a regulated private-operator market overseen by provincial authorities, while other provinces may use different structures. Players should confirm the rules that apply where they are physically located before depositing or playing.
Bankroll Management for a High-Volatility Slot
High-volatility games can consume a balance quickly when the stake is too large relative to the available bankroll.
A basic bankroll plan can include:
- Set a maximum amount for the session;
- Choose a stake before the first spin;
- Decide on a maximum loss;
- Establish a time limit;
- Avoid increasing the bet after losing rounds;
- Review the balance regularly;
- Stop when the predetermined limit is reached.
One simple way to estimate theoretical spin capacity is to divide the bankroll by the selected stake.
For example:
- CA$100 bankroll at CA$0.20 per spin: 500 spins;
- CA$100 bankroll at CA$0.50 per spin: 200 spins;
- CA$100 bankroll at CA$1 per spin: 100 spins;
- CA$100 bankroll at CA$2 per spin: 50 spins.
These figures exclude all returned winnings and only show how many consecutive stakes the starting balance can cover.
A smaller stake can extend the session, but it does not improve the RTP or probability of triggering Free Spins.
Bankroll and Stake Planning Matrix
Estimated spin capacity shows how many consecutive stakes a starting balance can cover before returned winnings.
| Starting Bankroll | CA$0.20 | CA$0.50 | CA$1.00 | CA$2.00 |
|---|---|---|---|---|
| CA$50 | 250 spins | 100 spins | 50 spins | 25 spins |
| CA$100 | 500 spins | 200 spins | 100 spins | 50 spins |
| CA$250 | 1,250 spins | 500 spins | 250 spins | 125 spins |
| CA$500 | 2,500 spins | 1,000 spins | 500 spins | 250 spins |
Calculation limits
Estimates exclude all winning returns, bonus credits, payment fees, promotion conditions and casino-level limits. A smaller stake extends theoretical capacity but does not change RTP or trigger probability.
Fairness and Random Number Generation
Each Bonanza result is produced by a random number generator. The software determines the reel heights and symbol positions independently for every new spin.
The random system means:
- Previous losses do not increase the chance of a win;
- Previous wins do not reduce the chance of another win;
- A long period without Free Spins does not guarantee an approaching trigger;
- The maximum Megaways layout can appear without producing a payout;
- A smaller reel configuration can still create a winning combination;
- Changing devices does not improve the mathematical odds;
- The time of day does not affect the result.
The game’s RTP and volatility describe long-term mathematical behaviour. They do not create a fixed sequence that players can identify or exploit.
Interrupted Spins and Connection Problems
If the internet connection is interrupted during a paid spin or cascade, the result is generally determined and stored on the game server.
Players should:
- Avoid pressing Spin repeatedly;
- Reconnect to a stable network;
- Sign back into the account;
- Reopen Bonanza;
- Check the current balance;
- Review the game or transaction history;
- Contact support if the result remains unclear.
A support request should include:
- Approximate date and time;
- Stake amount;
- Balance before the round;
- Device and browser;
- Description of the interruption;
- Screenshot, if available;
- Round identification number, where displayed.
Players should not repeat a deposit or wager until the original transaction status has been confirmed.
Responsible Play at Betty Casino
Bonanza should be treated as paid entertainment rather than a method of generating income.
Responsible playing practices include:
- Using only money that is not needed for essential expenses;
- Setting deposit, loss and time limits;
- Taking regular breaks;
- Monitoring total wagers rather than individual wins;
- Avoiding gambling while stressed, upset or impaired;
- Never borrowing money to continue playing;
- Not attempting to recover losses through larger bets;
- Using cooling-off or self-exclusion tools when necessary.
A player should consider stopping when:
- Spending exceeds the planned budget;
- Gambling interferes with work or relationships;
- Deposits are hidden from others;
- Losses create financial pressure;
- Playing continues despite no longer being enjoyable;
- Borrowed funds are used;
- Limits are repeatedly changed or ignored.
Eligible users can review the responsible gaming controls available through their Betty Casino account and consult recognized Canadian support services when gambling becomes difficult to control.
Safer Play Check and Canadian Support
Practical account controls, warning signs and confidential support resources.
Personal play check
Is the session using money reserved for necessities?
Gambling funds should remain separate from rent, food, bills, debt payments and emergency savings.
Has the original loss or time limit been changed?
Repeatedly increasing limits during a session can indicate that the planned level of control has been lost.
Are larger bets being used to recover losses?
Increasing the stake does not make a winning spin, maximum Megaways layout or Free Spins trigger more likely.
Is gambling affecting sleep, work or relationships?
Negative effects outside the game are a reason to stop playing and contact a confidential support service.
Is the activity still entertainment?
Playing to solve financial problems or generate dependable income creates a higher risk of harm.
Why Bonanza Remains a Recognizable Megaways Slot
Bonanza remains notable because it combines the original Megaways structure with cascading reactions and a persistent Free Spins multiplier. The reel layout changes continuously, creating a different number of possible winning combinations on every round.
Its main characteristics include:
- Six variable-height main reels;
- A separate horizontal reel;
- Up to 117,649 ways to win;
- Consecutive-reel symbol combinations;
- Cascading payouts;
- Dynamite Wilds;
- GOLD bonus symbols;
- 12 standard Free Spins;
- A multiplier that increases through bonus cascades;
- High volatility;
- Mobile compatibility.
The game is most suitable for adult players who understand that a high number of possible winning ways does not guarantee frequent payouts. The bonus feature can build significant multipliers, but it may also finish without producing a return greater than the triggering stake.
Before opening Bonanza at Betty Casino, players should confirm the live RTP, betting range, game provider, maximum payout, provincial availability and any promotional restrictions. Keeping the stake proportional to the available bankroll and applying clear session limits provides a more controlled way to experience the game’s variable reels and cascading mechanics.
