Bonanza Demo Slot

Launched in 2016, Big Time Gaming’s Bonanza demo slot led to a global change in the slot market with its innovative Megaways reel engine providing up to 117,649 ways to win. With the reels set into the hillside surrounded by a flowing waterfall, boulders and greenery, this gold mining-themed slot is a must-play for any gamers.

Overall rating

The first thing you’ll spot is the horizontal reel along the top of the grid where the mining carts rumble along, in and out of the mining tunnel. There’s a selection of dazzling, colored gems in purple, red, blue and green, alongside card royals, 10 and 9, dynamite wilds and gold ingot scatters gracing the reels.

Bonanza Specifications

The Bonanza layout differs slightly from the free slots layout, with a total of six reels including the horizontal reel that sits on the top of the grid. Up to seven symbols land on each reel, including one in each cart above reels two, three, four and five.

Wins are achieved by matching symbols on consecutive reels, regardless of height, from left to right, starting with the leftmost reel. The highest paying symbols are the multi-colored gems, with purple paying 50x stake when landing six on the reels.

Cascading wins add to the pot as symbols explode following every win to make way for more symbols falling in from above the reels and to the right of the carts. The Bonanza Return to Player (RTP) is 96%, which is a good percentage, while the volatility is categorized as high. Players will need some patience to score the bigger wins and potentially the maximum win of 26,000x bet.

Bonanza Bonuses and Features

Dynamite wilds substitute for all symbols except the scatters, only appearing in the carts across the top of the main grid. Gold scatters can appear anywhere on the grid in the base game, and spelling G-O-L-D will activate the Free Spins bonus. If players land any additional gold scatters, they will receive a further five free spins.

For the Free Spins bonus, players are awarded 12 bonus spins. Scatters only appear in the carts above the reels, and players can land three or four of these for an additional five or 10 extra free spins, respectively. Additionally, during the Free Spins bonus, there is an unlimited win multiplier that starts at one and increases by one for every cascading win.


The Bonanza slot demo is a hugely popular game, not least of all due to its 117,649 ways to win Megaways engine. Triggering the Free Spins bonus is definitely the star attraction here, with that incredible unlimited progressive win multiplier that allows players to inch their way towards the max win of 26,000x bet. Of course, as we mentioned, the Bonanza RTP of 96% is respectable and high volatility makes for an exciting experience.
