This is a 6-reel slot, which sets the colourful symbols against the stone blocks of a mine. There’s a water wheel to one side and a hut to the other. Look above the game and you see a mine cart passing 4 openings in the mine. This adds even more symbols to the mix as the cart carries further symbols along.
Players of the game at the best slot sites will see 6 high-card symbols and 4 bright gems on the reels. It’s a dazzling sight, but the Bonanza slot machine is very easy to follow, and simple to set up. Load it up on your PC, smartphone, or tablet, and click the left and right arrow buttons to adjust your bet to anywhere between 0.20 and 500.00 per spin.
Other control buttons activate the Autoplay mode, and the 3 little lines on the panel open the paytable. It lists how much you win from each symbol when you match at least 3 on adjacent reels from the left.
It also explains the Megaways system, which randomly places between 2 and 7 symbols on each reel. That gives you between 64 and 117,649 different ways to line symbols up for a win.
Apart from the control buttons moving to where thumbs and fingers can reach them more easily, the mobile slot version of Bonanza is exactly the same as the desktop version. You can play Bonanza on iOS and Android devices without any compromises.
The Megaways format isn’t the only feature you’ll encounter in the base games. The Bonanza slot from Big Time Gaming also comes with what they call Reactions. Other developers call this cascading, or tumbling reels, but it’s the same thing. Winning symbols vanish from the reels and the ones above drop down to fill the void.
This can create new wins, which in turn trigger further Reactions, and so on until no new combinations appear. It’s a great way to grab several wins in a row. A bundle of dynamite is a wild symbol that acts as others if needed, boosting the number of winning spins.
Look out for the mine cart above the 4 middle reels, as it can add even more symbols to the mix.
The letters G, O, L, and D across the reels will help real money slot players win big, triggering 12 free spins. As well as a chance to collect prizes with no risk, there’s a rising multiplier in effect during the round. Any series of Reactions sees the win multiplier rise by 1x, so 5 wins in a row, for example, would see the last prize multiplied by 5x over.
Any 3 or 4 scatter symbols appearing in a free spin will add 5 or 10 extra games to the total number of bonus games. And check out our online slots bonuses to see what offers you can land when you sign up to play.
The white diamond symbol pays 50x your total stake when it crosses all 6 reels. But if it’s part of a win in the free spins round, with a multiplier, the value shoots up. Max payouts are set at 10,000x your stake, or a massive 5,000,000.00 when you have 500.00 on the triggering spin.
This is a high-volatility game, with an average payback percentage of 96%.
Bonanza certainly packs a lot into its 6 reels. The Megaways, Reactions, and free spins with multipliers ensure excitement from spin to spin. We were a little disappointed in the choice of symbols, and prefer games with more images connected to the theme, but it didn’t put us off enjoying the Bonanza slot.
If you want a game where everything is linked to a mining theme, play the Bomb Bonanza slot from Pragmatic Play.
