Prepare for a mining adventure in the Bonanza Billion online slot game at Mate Slots Online. This western-themed slot brings miners, mountains, mine carts, dynamite, and more to every spin. With ways to win up to 117,649 times your bet, Bonanza Billion serves up endless excitement.
Bonanza Billion slot has 117,649 ways to win thanks to its unique Megaways game engine. Instead of paylines, winning combinations are formed when matching symbols land adjacent to each other on the reels. As long as symbols touch horizontally or vertically, they count as a win. With symbols expanding to fill the entire reel and extra symbols added with each spin, Megaclusters form often. The more symbols in each cluster, the bigger your payout. Even clusters with just 3-4 symbols award decent wins thanks to the bonus multipliers. During free spins, all wins get a 2x multiplier applied to dramatically boost your bankroll.
To trigger Bonanza Billion’s free spins round, you need to land 3 or more scatter symbols on the reels. The scatter is the Gold Fever icon with XXXX on it. When 3 scatters land, you get 8 free spins. 4 scatters awards 12 spins, while 5 scatters gives 20 free spins. During free spins, the reels become more volatile with extra wild symbols added. Any wild that lands stays frozen in place for the remainder of the spins too. All wins during free spins come with a 2x multiplier. If you trigger more scatters, you retrigger the bonus round and reset the number of spins.
