Bonanza Billion Demo & Review

Bonanza Billion review

Bonanza Billion was BGaming's first cascading-reels game, a fruity pay-anywhere slot where the number of matching symbols on screen at the end of a spin decides the win. Winning symbols are cleared and the reels refill.

Four, five or six scatters award 10, 20 or 30 free spins, and three scatters during the bonus add five more. Multiplier symbols worth 2x to 100x appear only in free spins and stay on screen until the refill sequence ends, when their values are added together and applied to the win. Chance x2 and a bonus buy are available where permitted. BGaming lists a 15,000x maximum. The RTP is 95.97%. The free spins are rare (about once every 395 spins), so this is a game for patient players.

Bonanza Billion RTP, volatility and max win

RTP: the default return to player is 95.97%, meaning that over a very large number of spins the game is designed to pay back around 96.0 units for every 100 wagered. Some casinos may run a lower configuration; the info screen inside the game shows the exact figure. How RTP works.

Volatility: The provider hasn't published an official volatility rating for Bonanza Billion, so we don't label it. Judge it from the demo: if wins are rare but bonus rounds carry most of the value, treat it as a higher-variance game and size your stake accordingly. Volatility explained.

Max win: the maximum payout is 15,000x the stake. What max win really means.
