About Bonanza Slot

The Bonanza slot is one of the most popular online casino games in the world, and Big Time Gaming are the legendary developers behind the Megaways slots phenomenon. Set across a hilly landscape, Bonanza is themed around the gold mining industry, and there’s plenty hidden throughout the reels and features.

There are lower-paying symbols themed around playing cards, of 9, 10, J, Q, K, and A, while the higher paying symbols are made up of Emeralds, Sapphires, Rubies, and Amethyst gemstones. The Dynamite is the wild, which can substitute for most other symbols on a payline, and the letters G-O-L-D work as the scatters. If all four appear, the Free Spins bonus round will be triggered.

BONANZA Top Features

Big Time Gaming’s Bonanza is the first game to ever feature the provider’s proprietary Megaways system. We’ll walk you through the best features that this gamechanger has to offer.

Bonus Features

After completing a winning combination, all of the winning symbols are removed from the reels and new symbols cascade from the top of the grid to take their place. If you make a new winning combination, the process repeats itself. Cascade reels stop running once you have no new wins on the reels.

In line with the slot’s mining theme, you need to spell out the word GOLD anywhere on the reels to trigger free spins. You start with 12 bonus rounds but can add another five to your tally for every extra triggering scatter. The biggest addition during the bonus rounds is the inclusion of the win multiplier. Whenever you hit a cascade win, the multiplier is increased, and you could theoretically increase this with no limit.

Landing more scatter symbols during free spins increases the duration of the bonus mode. Three or four gold scatters award five or 10 free spins respectively and there’s no limit to the number of free spins you can continue to add.

Megaways with its dynamic reels and cascade feature is a unique element for Bonanza. Having a maximum of 117,649 ways to win means its more possible to hit the game’s maximum win of 26,000x your stake. Bonanza also comes with an incremental win multiplier which grows with each new cascade win you hit during free spins.

Bonanza Slot Features


A commonplace feature in Megaways UK casino games, Reactions see winning combinations removed from the reels, and new symbols drop into their place. This can lead to further wins, and there is no limit as to how many times this can happen consecutively.

Free Spins

If you land each of the letters G-O-L-D across the reels, you will trigger the Free Spins bonus round. 12 will be awarded as standard, with 5 additional spins rewarded for each additional scatter that triggers the round. Further Free Spins can be added during the round if three or four scatters appear in the top reel. There’s also an unlimited win multiplier in play that will start at 1x and increase by 1 with every Reaction.

What Symbol Gives You the Biggest Win?

Purple diamonds are the highest-paying symbols in Bonanza. They give you a huge win of 50x your stake when landing six of a kind.

How big can the multipliers go?

There is no limit to how big your win multipliers can get. Bonanza’s free spins have a recurring win multiplier that increases by a value of one with each new cascade win you make. The game has no limit on how high this can get, so the more cascades you manage to have during the bonus round, the bigger the multiplier will get.
