Bonanza Review

The Bonanza slot from Big Time Gaming is notorious for kicking off the Megaways craze. Launched in December 2016, the game is part of the series that includes White Rabbit and Danger High Voltage, which both came out in 2017. Coming with a mining theme, this eye-catching slot features 6 reels and as many as 117,649 paylines. Despite having high volatility, we found Bonanza to be hugely entertaining, with the highest rewards being won through bonus rounds. With Bonanza being the most popular slot in the BTG portfolio, in the same way as Starburst is to NetEnt and Mega Moolah is to Microgaming, we had our experts take a closer look.

Bonanza Free Spins

While playing Bonanza, we discovered that four scatters, which turn gold, must be landed in order to unlock free spins. If you do so, you are automatically awarded 12 free spins. Meanwhile, another 5 free spins are delivered for each additional scatter landed. This means that even before the bonus round has been activated, a good number of free spins can be won, something we feel makes Bonanza hugely appealing.

Free spins are collected in the event of carts above the reels stopping with gold bars inside during the bonus round. 5 extra spins are awarded for three in a cart, with four in a card adding up to 10 free spins!

More Features & Wager Limits

Elsewhere, the cascading reels feature was activated frequently while we played Bonanza. As is the case with many video slots today, including Temple Tumble Megaways from BTG, this mechanism results in winning combinations being replaced by new symbols. Should another winning combo land, additional winnings are delivered. This situation can repeat a number of times, with the highest payout being 10,000x.

The Dual Reaction feature was another pleasing aspect of playing Bonanza. Here, the action begins with winning symbols exploding into pieces on the six main reels before being replaced by new falling symbols. Lucky players can potentially repeat this any number of times.

Bets at Bonanza are available between $0.20 and $500 per spin, which really does cater for all types of players but especially for high rollers. With an RTP of 96%, it is clear to see why Bonanza has been a firm favourite since its release.

Bonanza Slot Design & Music

Given the mining theme, you will not be surprised to hear that Bonanza is set in a quarry, with symbols being firmly embedded in the stone. While not being particularly vibrant in terms of colours, things quickly improve with the help of special symbols and bonus rounds. Another thing we enjoyed about Bonanza was the speed of the reels, which ties in nicely with the Wild West-style soundtrack, with lasso and pistol sound effects adding to the fun. The sound of the coins increasing was particularly pleasing too!

Review Summary

The Bonanza video slot really helped to put Big Time Gaming on the map. It is clear to see why Bonanza was an almost instant hit, with the free spins, cascading reels and Dual Reaction features being particularly rewarding. While not being anything new in terms of its theme, Bonanza comes with an authentic design, featuring exploding gunpowder and prized jewels, that includes high-quality graphics. In our experience, Bonanza works well on desktop, mobile and tablet, with a free-to-play version also being available. Overall, there is little we didn’t like about Bonanza, with the lack of a progressive jackpot not even being a major issue, given the large number of paylines.
