Slot Summary

Big Time Gaming places Bonanza near the center of its Megaways identity, using variable reel heights and reacting wins as the game's defining rhythm. The six-reel mining slot can open as many as 117649 win ways, then remove winning symbols and feed replacements from above and from the right. Its 96% RTP sits beside medium volatility, but the decisive feature is the free-spins multiplier that increases after each cascade.

How It Plays

Bonanza uses six changing reels rather than a fixed number of symbols on every spin. Each reel's height helps determine how many of the available 117649 win ways are active.

A completed win removes its contributing symbols. New symbols then enter from two directions, allowing the same paid spin to produce another combination before the reels finally settle.

Theme & Atmosphere

Wild West, Gems and Treasure themes meet in an underground mining setting. Bomb imagery supports the removal of winning symbols, giving each cascade a practical connection to the subject.

The Action and Adventure treatment remains secondary to readability. Gems, mining equipment and exposed treasure make high-value symbols distinct while the changing reel heights remain easy to follow.

Wild West Action & Adventure Gems Treasure Bomb

Features & Win Potential

Megaways changes the number of symbols shown on each reel from spin to spin, creating a variable count of active win ways that can reach 117649.

Cascading removes every winning symbol and replaces it from above and the right. The process repeats for as long as each replacement produces another qualifying combination.

Bonus & Free Spins

Scatter symbols open free spins, where every cascade increases the win multiplier. Unlike the base game, that multiplier remains active for subsequent spins in the same feature.

Stacked scatter symbols can extend the round. Three stacked scatters add 5 free spins, while four stacked scatters add 10, increasing the number of chances to raise the multiplier.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (26,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
