96.00% RTP




The online Bonanza slot machine by Big Time Gaming is a virtual trip to the gold mines with 117,649 Megaways to win. Plus, unique Bonanza slot game multipliers that skyrocket up to 10,000x your stake, thanks to the free Bonanza games (free spins), changing ways to win and other bonus features.




The setting and theme is a gold mine entrance with six irregular reels, each consisting of three to six symbols. Then there’s an extra 4-symbol row of symbols above the grid which cascade down with each combo win and are instantly replaced with new symbols. Big Time Gaming calls this the DUALRECATION feature. As you explore the symbols with winning combos you also break the rocky exterior. Bonus features darken the screen and you find yourself in a red cave.

The lower-paying symbols are your standard K-9 card values. While the higher-paying symbols are the gems: the opal, sapphire, ruby and emerald symbols. The lit TNT is the Wild which can substitute all other symbols except the gold scatter symbols. Literally, four different gold letter symbols that spell out the word GOLD. A combo of four or more of these symbols will trigger the free spins feature, which is where you can win the biggest multiplier prizes.

You start off with 12 free spins and after every win reaction, your multiplier will increase and increase. Thanks to those TNT Wilds and up to 117,649 ways to win, you can actually hit quite high wins in this Bonanza online slot.




The 6x7 reel in Bonanza slots grid offers up 117,649 ways to win and pays left to right for most 3 or more combo symbols that you land. There are many ways that help create cascades of wins and increase your prospects with consecutive action.

Find the word GOLD using four or more gold letter symbols (scatters) across the reels and you will trigger 12 free spins. Here on every reaction (win) your multiplier will increase starting from 1x. You can get more free spins by finding 3 or more scatters in the top row of four symbols.

In fact, any extra scatter in the Bonanza slot online adds five extra free spins to your round. And the amount of multipliers are continuously escalating with each trigger, which keeps the Bonanza casino game exciting from start to finish.

All in all, there’s a decent Bonanza slot RTP and the game is high volatility, so you can expect frequent action. Most of it will be the lower-paying combos, but if you do eventually hit the free spins feature, it’s worthwhile. All you have to do is decide the stakes and spin at will.

Note that this is a game of chance, and there is nothing you or Betfair can do to increase the Bonanza RTP (return to player). It is all randomly generated, so the game should be viewed as a fun pastime with a possibility of winning, instead of just a way to make a profit, as there are no guarantees.
