Bonanza is a mining themed slot from Big Time Gaming. It’s arguably Big Time Gaming’s greatest hit and was one of the first to introduce the Megaways format. We’re going to cover more on these Megaways along with what else this slot has to offer.
The title Bonanza doesn’t really allude to anything particular. But upon opening it, you’ll quickly find that it’s a mining themed slot.
The background looks excellent. Rather than actually taking place inside of the mine, it happens on a mountain side. The reels are fashioned to look like rocks on the mountain. The top of the reels feature mining carts that roll by and serve as extra symbols.
Speaking of symbols, they include a wild, various gemstones, and letters. The most-notable letters are G, O, L, D. When spelled out across the reels, they combine to trigger free spins. The purple gemstone pays the most at 50x your stake.
The Megaways format alludes to how this slot can offer numerous ways to win in any round. Each reel can feature between three and seven symbols. Assuming each reel has seven icons, then you’ll unlock the maximum of 117,649 ways.
Return to player (RTP) for this slot is 96.0%. Betting options range from €0.20 to €20. You can use autoplay to keep the reels spinning with your chosen betting preferences.
Cascading Reels – Symbols from winning combinations disappear. Meanwhile, icons from above fall into the empty spaces. This cascading effect continues until no more wins can be formed.
Free Spins – This bonus is triggered by spelling G-O-L-D on the reels. You receive 12 free spins to start and can add five more with a +5 icon.
Unlimited Multiplier – Every free spin starts with a 1x multiplier. This unlimited multiplier continues increasing by 1x with each subsequent cascading win.
The main reason why many players have fallen in love with Bonanza is because of its numerous winning possibilities. You can look forward to up to 117,649 ways.
But this game has more to like than just its sheer number of payout opportunities. Bonanza slot also offers multiple features and a great atmosphere.
The features include cascading reels, free spins, and an unlimited free-spin multiplier. These bonuses combine to enhance your potential payouts greatly.
The background graphics are excellent. This slot takes place on the side of a mountain, which puts a new spin on the mining theme. The only real downside to this game could be the music. It’s a repetitive banjo tune that becomes grating after a while. But you can always mute the music and enjoy an otherwise great slot.
