For all intents and purposes, the Bonanza slot Big Time Gaming release is themed around mining. At the start, you are introduced to the side of a cliff where precious gems and symbols are exposed. As you can imagine, the aim of the Bonanza slot is to mine those rewarding gems for winnings.


When playing Bonanza, it is useful to look at the paytable first. In the Megaways section, it is revealed that some symbols can cover more than one position. This is also where you will learn that there are no paylines included in the game.

If you want to win on Bonanza, then you are going to have match symbols in adjacent reels, and there are six of those in total. As you can imagine, there are numerous ways to win, given the configuration of the game. In fact, there is a staggering 117,649 Megaways to win.


When looking at the paytable, it will soon become clear that the multipliers are lower than for other slots, but this is because Bonanza has so many ways that you can win from. To earn the highest winnings, you should aim to combine six of these symbols:

  • Purple gem: 50x
  • Red gem: 7.5x
  • Blue gem: 2x
  • Green gem: 2x


Big Time Gaming has integrated a wagering system that allows players to stake values ranging from £0.20 up to £20.00. You can even assign auto-play criteria, with Bonanza letting you pick the number of spins, loss limit, and single win limit. Once a limit has been reached, the auto-play feature shall stop at once.


Bonanza is even more exciting when you can benefit from the special features. These can be combined in different ways to earn winnings:

  • Carts: Mine carts are positioned above the second, third, and fourth reels. Once a winning chain is created below, there is a chance for the items in the mine carts to drop down to the lower levels and become activated.
  • Win reactions: After a winning chain is created, the symbols disappeared to be automatically filled by the ones resting above.
  • Wilds: The wilds are even more exciting in Bonanza, as these symbols are burning dynamite sticks and can substitute for other symbols.
  • Free spins: Land five GOLD scatter symbols and you will receive 12 free spins. During this time, you can land another scatter and receive an extra five free spins. Playing the Bonanza slot free is even more appealing.
  • Unlimited win multiplier: In free spins, you can keep on winning thanks to the unlimited win multiplier that becomes activated.


The game is a little pixelated on desktop devices, but the Bonanza slot mobile interface is the perfect size, and the game works extremely well. Plus, you can also try out a much more innovative experience compared to standard five-reel slots.


Strategy can definitely have a place in slot games, and here are some suggestions to consider:

  • Create winning chains: The base game multipliers are low, so it’s all about creating winning chains to allow for other symbols to automatically drop down.
  • Target free spins: These should be your ultimate target, as it’s quite straight-forward to keep on triggering them. At the same time, you can have the chance to benefit from the unlimited win multiplier.


To sum up this Bonanza slot review, the theme has been extremely well-realised, with Big Time Gaming truly making this feel like a mining experience. And while the base game symbols are quite low, there are several special features to make up for this, especially the free spins and the unlimited win multiplier.
