Bonanza Slot Review

The Bonanza slots game can be found at casinos using Big Time Gaming software. Big Time Gaming is one of the newer software developers in the online gaming market. Alongside many of the smaller casino software providers Big Time Gaming focus exclusively on Slot Games. The company was founded by two individuals who reportedly were involved in the early days of New Tech Media that (via various sales and takeovers) ended up being part of OpenBet. Big Time Gaming publish the slots house edge information of all their games as standard. As such we can say that the House Edge of Bonanza is 4%.

Bonanza is a 6 reel slots game that is 3 symbols high. However, the number of symbols that make up a reel can change at random, with the potential for each reel to contain 7 symbols. The game does not use traditional paylines, instead it operates with a maximum of 117,649 different possible “megaways”, playing from left to right.

Carts – Above the reels there is an additional set of symbols that sit inside a traditional mining cart. This adds a symbol above reels 2, 3, 4 and 5 to help create additional wins.

Special Symbols

Wild – The Wild symbol is the “Dynamite”, which will substitute for all symbols other than Scatters.

Scatters – The “Gold” symbols are Scatters. To trigger the game’s Free Spins feature you need to spell out “G”, “O”, “L”, “D”, across the reels, with the Scatter symbols. When you do so you will be granted 12 Free Spins with 5 additional Free Spins for every extra Scatter symbol that you land.

Bonus Features

Reactions – Every time you land a winning combination the symbols involved will explode and are replaced by a new set of symbols, giving you an additional chance to win. Reactions will continue until you fail to land a winning combination.

Free Spins – During the Free Spins feature, for each reaction that you land you will be awarded a win multiplier, which will increase by one after each reaction.

Free Spin Scatter – The Free Spin Scatters are carts filled with gold and will only appear in the carts set above the reels. 3 Scatters will win you an additional 5 Free Spins and 4 Scatters will win you an additional 10 Free Spins.


Bonanza is set deep inside the heart of a working gold mine. All the symbols reflect this, from the sticks of dynamite to the gems and gold that they help to release. The game looks good with the mine acting as the reels and the background, an idyllic countryside picture framing the mine. The game has Free Spins and Wilds with reels that can change, plus the additional symbols that sit in the carts above the reels. Whilst that sounds like there is a lot going on it still feels as though something is missing; a bonus feature or progressive jackpot. At 4% the house edge is far from poor value for money but at the same time we always want to see better than this. All things considered, this is a solid game in all respects, not amazing, but doing everything it does well.
