Play Bonanza Billion in Demo mode or for Real Money
Bonanza Billion is a BGaming slot with RTP 96% and high variance. The theme is a gold mine: dynamite, gems, mining carts. It works like this: the game runs on Megaways mechanic, up to 117,649 ways to win on every spin. The Bonanza Billion game also has cascading wins — symbols that form a combination disappear and new ones fall in their place. One spin can pay several times in a row. And that is where everything that actually matters happens.

Cascading wins keep triggering as long as new combinations land. Three or more scatter symbols anywhere on the reels start the free spins.

Special Features
In free spins the Bonanza Billion multiplier starts at 1x and grows by 1 with every cascade. There is no cap on the multiplier.

- Play Bonanza Billion free to get a realistic sense of how cascade chains behave before moving to real money
How Bonanza Billion Plays Out
Bonanza Billion is built around one idea. An unlimited multiplier that grows with every cascade during free spins. The base game is interesting enough on its own but the bonus is where sessions go one way or the other. Play Bonanza Billion at Mateslots, try the demo first and move to real money when the mechanic is clear. Set a budget before the session starts and play responsibly.
