Bonanza info
Bonanza, developed by Big Time Gaming, helped revolutionise online slots. Set in a peaceful mining canyon with flowing waterfalls and a wooden cabin built into the rocks, it hides something far more dynamic: one of the earliest games to showcase the Megaways mechanic.
Inspired by gold prospecting, the slot’s background features grassy slopes, mine carts on rails, and symbols that resemble precious gems and classic card values. You’ll hear birds chirping, tools clanking, and a lively banjo tune that plays whenever the reels spin into action.
Bonanza’s return to player (RTP) rate sits at 96%, and it comes with high volatility. The game runs smoothly on both desktop and mobile, adjusting well to any screen size while keeping gameplay consistently enjoyable.
Unlock Thousands of Ways to Win
The Bonanza grid is split between six vertically spinning reels and what looks like a seventh reel that spins horizontally above them. This seventh reel consists of carts moving across a track. Symbols in each cart form the top row of the slot’s four middle reels in a setup that’s found in many slot games with the Megaways mechanic.
To start playing Bonanza online, launch the game and click the green spin button. You can change the base stake at the start of a new round by clicking the left and right arrows beneath the bet box.
Once the reels have stopped spinning, winning combinations in view will pay out. Afterwards, any triggered bonus features or rounds will play out.
The Bonanza slot has 10 standard symbols that award the slot’s payouts. Winning combinations are formed whenever matching symbols land on adjoining reels, beginning with Reel 1.
Diamonds are the only symbols that pay with a minimum of matches. All others require a minimum of three matches.
Payouts from diamonds range between 2x and 50x the base stake, whereas those from red gemstones range between 1x and 7.5x.
Wilds are present throughout the game and substitute standard symbols to create or develop winning combinations. These symbols, however, cannot substitute scatters and don’t provide any additional payouts.
Bonanza Features
Bonanza stands out at our online casino thanks to its unique mechanics and engaging gameplay. From cascading wins to expanding ways to win, each feature adds intrigue to every spin.
Reactions
Whenever a winning combination is present on the Bonanza slot, it triggers a reaction. Winning symbols pay out before disappearing, causing symbols above them to cascade in their place. New symbols, meanwhile, are added from above to fill any gaps.
Reactions increase the likelihood of forming multiple winning combinations in the same spin. Moreover, they keep occurring until there are no winning symbols in view.
Bonanza Free Spins
Four gold scatter symbols that together spell the word GOLD trigger a round of 12 free spins. Any additional triggering scatter adds five extra spins to the balance.
During free spins, reactions increase the base multiplier by 1x. There is no maximum cap on this multiplier, and its value is applied to all free spin winning combinations.
You can retrigger free spins by landing three or four scatters on the top row of the middle reels. Three scatters award five extra spins, while four grant 10 more.
There’s no limit to how many times you can retrigger the bonus, as it keeps going until you run out of spins or hit the maximum win limit. Moreover, when free spins begin, any wins during the feature are multiplied by your original base stake.
