Game rules

Bonanza is a mining-themed game in which six reels spin vertically offering up anything from 1 – 6 rows of symbols with each game. Meanwhile the mining truck runs from right to left across the top of the reels, adding extra symbols to the central rows, providing up to 7 rows in total. This means the number of Ways to Win varies with each spin, giving up to 117,649 Ways in total.

Bonanza symbols

Traditional playing card icons make up the lower value symbols on the Bonanza paytable, with emeralds, rubies, sapphires and diamonds awarding the bigger prize payouts. There are Wild sticks of dynamite that will help you create winning combos across the reels, along with four gold Scatters spelling out the word G-O-L-D. Land all four to trigger the bonus game, with extra gold Scatters awarding even more free spins throughout the bonus round.

Min/Max wagers & lines

There are no paylines in Bonanza, as this is a Megaways slot. You’ll need to match up winning symbols on adjacent reels from left to right to win a cash prize, and the number of rows in each reel changes with every spin. The minimum cost of a spin is £0.20 rising to a maximum bet of £20, which gives betting options for most types of slots fans.

Key Game Features

Pay table & bonus rounds

Low value symbols barely return your stake for landing five of a kind across the reels, but with up to 117,649 Ways to Win with each spin you’ll be hoping to spin up multiple cash prizes with every game. The diamond pays out the most, returning up to 50x your stake for five on adjacent reels, but every win rewards you with extra chances to win thanks to the Cascading Reels mechanic.

Cascading Reels make winning symbols disappear, leaving empty spaces on the grid. New symbols drop down, effectively giving you a free Respin, which could in turn provide more winning combinations. You won’t have to pay to spin the reels again until no more winning combinations land, unless you’re playing the Bonanza demo of course, in which case you won’t pay for any spins – but you won’t benefit from actual cash prizes either!

Spell out the word GOLD with Scatters to activate the Bonanza Free Spins Bonus. Now you’ll venture deeper into the mine for 12 free spin, with an Unlimited Multiplier to help you amass your prize pot. Every reaction from the Cascading Reels adds 1 to the multiplier, so you could reap some huge rewards by the end of the bonus. And with extra gold Scatters awarding 5 more free spins, this is the round that players are hoping to trigger.

Animation, graphics, and soundtrack of bonanza

Whether you opt for Bonanza free play games, or you choose to wager your own money on your spinning session, a good time is pretty much guaranteed thanks to the talented artists at Big Time Gaming. A peaceful hillside setting with a huge water wheel is the background setting, with the reels set within blocks of stone taking centre stage. It’s all very bright, breezy and colourful, and there’s an engaging hillbilly soundtrack to add to the fun.

Bonanza RTP and volatility

The Bonanza slot RTP comes in at an extremely pleasing 96%, which is identical to the Buffalo Gold slot RTP, giving a house edge of just 4%. This figure suggests that there should be good prize-winning opportunities, although sadly not for all players. More important than the Bonanza RTP ratio is its high volatility, so you can expect plenty of non-winning spins or low value wins for the most part - although someone has to be the lucky player who lands that 10,000x top prize!

Bonanza verdict

Bonanza is such an iconic game that it really deserves to be played by everyone, even if only in demo mode. The Cascading Reels can generate multiple wins from a single spin, with the bonus rounds providing the opportunity to generate some seriously big cash prizes for some lucky players. We’ll guide you towards the best Bonanza slot sites where you can play for free, before moving onto real money wagering if you find it’s a game you’d like to play with real cash.
