Mechanics of Bonanza Billion

The game starts with a standard 6-reel layout where each reel shows between 2 and 7 icons. Every winning combination removes those elements from the grid and new ones fall into place. This cascade system continues until no more wins appear on the screen. Four or more scatter symbols unlock the free spins round. Users get 12 initial spins plus 5 extra spins for each additional scatter beyond the fourth one. The multiplier starts at 1x and grows by 1 with each cascade during the bonus round.

Special Characteristics

These mechanics work together to create chains of wins. The mystery icons appear randomly on any spin and change into the same element type. Wild multipliers only show up during free spins and stick to the reels for the entire bonus round. The title includes several features that boost winning chances:

• Mystery Symbols – Question marks that transform into matching icons

• Wild Multipliers – Wild elements that multiply wins by 2x or 3x

• Buy Feature – Direct access to free spins for 100x the stake

• Gamble Option – Double or nothing game after any win

• Autoplay Mode – Set up to 1000 automatic spins

Betting Variations and RTP

Bonanza Billion accepts bets from £0.20 to £20 per spin. The return to player rate sits at 96.00% which matches industry standards for online slots. High volatility means wins come less often but pay more when they hit. The maximum win reaches 10,000x the stake amount. This cap applies to both base game spins and bonus rounds. Gamblers at casino Rainbet can hit this limit through multiple cascades with growing multipliers during free spins. The activity includes a quick spin option that speeds up the reels for faster gameplay sessions.
