Bonanza Megaways
Bonanza Megaways is the Big Time Gaming slot that introduced the Megaways mechanic to the industry. Played across 6 reels with up to 117,649 ways to win, it features a Reactions cascade mechanic, an unlimited win multiplier during free spins, and a 26,000x max win ceiling. The standard RTP is 96.00% and volatility is high, which means sessions are driven by bonus entries rather than steady base-game returns. Its release defined an entire genre and dozens of later titles are built on the same licensed engine.
Key takeaways
- RTP: 96.00% standard. Confirm in the game's info panel at your casino as operators can licence alternative builds.
- Volatility: high. The base game pays modestly between bonus entries; the free-spins multiplier is where the largest wins come from.
- Max win: 26,000x your stake, reached through a sustained unlimited multiplier climb in the free-spins round.
- Megaways: each spin produces a random number of symbols per reel, changing the ways-to-win count up to 117,649 on any given spin.
- Reactions: winning symbols are removed and replaced from above or from the mining-cart symbols on top of the middle reels, enabling chains of consecutive wins from one spin.

How Bonanza Megaways works
Bonanza uses six reels plus a row of symbols in mining carts above the four middle reels, giving it an unconventional layout. The Megaways engine produces a random number of symbols on each reel per spin, which changes the ways-to-win count with every play. The top row adds further symbol positions, so the grid is not fixed in height or structure from spin to spin.
Winning symbols are cleared by the Reactions mechanic, and new ones drop from above to fill the gaps, or slide in from the mining carts on the top row. Each consecutive Reaction from the same spin can form a new win, and chains of Reactions from a single spin are where the base game produces its larger pays.
What high volatility means for your session
High volatility on Bonanza means the majority of spins return modest amounts or nothing, with value concentrated into bonus rounds and occasional strong Reaction chains. The base game is not designed to grind out steady returns. Sessions without a significant win can last many multiples of what you might expect from lower-volatility games.
The correct approach is to set a stake and a session budget before you start, play at a stake size proportional to that budget, and treat the free-spins entry as the target rather than expecting the base game to sustain the balance. Adjusting stakes mid-session to recover a deficit compresses those dynamics into a shorter timeframe, which does not improve the outcome.
Free spins and the unlimited multiplier
The free-spins round is the game’s main event. Each Reaction during the feature adds 1 to the running multiplier, and there is no ceiling on that multiplier. A round that triggers a long unbroken chain of Reaction wins will finish with a high multiplier applied to the final wins in the chain. That is the mechanism behind the 26,000x ceiling: a combination of a strong win alongside a multiplier that has climbed through many Reaction steps.
Retriggering extra spins by landing additional scatter symbols during the round extends its duration and gives the multiplier more opportunities to climb. Well-retrigger rounds with sustained Reaction chains represent the game at its best.
The mining-cart top row
The mining-cart symbols on top of the middle four reels are a small but meaningful design element. They add extra symbol positions that can contribute to Reactions and affect the ways-to-win count for those reels. Because the carts can carry high-value symbols, they participate in winning chains from the top of the grid down, which is different from most standard reel formats. It gives the game a slightly wider winning area than a flat 6x4 layout would.
Staking sensibly and where to play
Bonanza Megaways is best suited to players who understand that most of its value is in the free-spins round rather than the base game. Given its high volatility and the absence of a bonus buy, patience through the base game is the only path to the feature. Casinos in our crypto casinos and fast-payout casinos lists offer fast settlements when the multiplier climbs.

Frequently asked questions
What is the RTP for the Bonanza Megaways slot?
The RTP of Bonanza Megaways is 96.00%, in line with the mainstream slot average. Big Time Gaming is distributed through Evolution, and lower-RTP operator builds exist at some casinos. Always check the info panel inside the game at your specific casino, as the displayed figure is the one that applies to your session.
How does the Megaways system work in Bonanza?
Megaways is a patented Big Time Gaming mechanic in which each reel displays a random number of symbols on every spin, typically between 2 and 7. Multiplying the symbol counts across all active reels gives the total ways to win, which in Bonanza can reach 117,649. An additional top row of symbols above the four middle reels contributes further positions. Because symbol counts change on every spin, the ways-to-win total is different on every play.
How does the unlimited multiplier work in free spins?
When free spins are active, the win multiplier starts at 1x and increases by 1 with each Reaction cascade that produces a win. There is no cap, so a long chain of consecutive winning Reactions can push the multiplier into double or triple digits before it applies to the final winning combination. This uncapped climb is the primary route to the game's 26,000x ceiling.
How do you trigger free spins on Bonanza Megaways?
Four or more scatter symbols represented by the gold letters spelling GOLD trigger the free-spins round. The scatters can appear anywhere on the reels, including the mining-cart positions above the four middle reels. Additional scatters landing during the feature retrigger extra spins, allowing the multiplier more opportunities to climb.
Is Bonanza Megaways still worth playing?
Bonanza holds up against newer Megaways titles because its unlimited free-spins multiplier is generous by the standards of the genre and the 26,000x ceiling is substantial. The base game is quiet, which is typical of high-volatility slots built on this engine. Players new to Megaways will find it a cleaner reference point than later titles that layered additional features on top of the same engine.
Does Bonanza Megaways have a bonus buy?
No, Bonanza Megaways does not include a bonus buy option. The only route to free spins is through the base-game GOLD scatter trigger. Later Megaways titles built on the same engine added bonus buys where regulation permits, but the original Bonanza relies entirely on the natural scatter landing path.
