How to play Bonanza mobile slot

Head to the gold mines in this 117,649 Megaways to win Bonanza slot and you could be in for some big wins up to 10,000x your stake, thanks to Free Spins, Multipliers & changing ways to win.

Set deep in the bedrock of the gold mines, this 6 reel and up to 117,649 ways to win Bonanza slot game offers you up to 7 symbols per reel, and pays for most 3 or more adjacent symbols that show up from left to right.

Much like their space themed Star Quest slot.

However, here there are some major differences that help create cascades of wins or have you prospecting for more.

Extra carts and dual reaction wins

Above reels 2, 3, 4, and 5 are carts each filled with more jewels and symbols, these act as another reel and can help create combination of wins.

However, it’s the cascading reels system, like you might find in Microgaming’s Jungle Jim slot game or NetEnt’s Gonzo’s Quest, that will provide you with some fast paced action of multiple consecutive wins.

Big Time Gaming are calling this a DUALREACTION feature, where not only do the main 6 reel winning symbols explode and more fall in from above, but new symbols that were part of the carts will roll in from the right and fill up with (hopefully) more winning symbols.

An interesting concept that whilst it takes a moment of two to get your head around, does help create more wins – though not always particularly big wins.

That’s where the Bonanza slot free spins come into play.

Unlimited free spins with unlimited multipliers

Well that’s the theory anyway, but only if you are incredibly lucky. You actually start off with 12 free spins for finding the golden letters G O L D across the reels, and are taken to a darker night time setting.

Here, after every reaction or win found, your multiplier will increase up to an unlimited amount – but only in theory. You can expect to reach about 5x – 10x on average, which is still not bad.

There’s also the chance to get more free spins by finding the gold bar scatters in the carts at the top of reels 2, 3, 4, and 5.

It will take you a little while to hit these Bonanza free spin games, but when you do you’ll more than likely be walking away with a little extra cash in your pocket thanks to those wilds, and up to 117,649 ways to win.

Bonus Features

Wilds:The lit TNT is wild and substitutes for all other symbols except the golden scatters.

Carts: The carts roll in from the right and stop on reels 2, 3, 4 and 5 to add an extra symbol. These help create more slot wins and bigger payouts.

DUALREACTION: On a win the symbols used in a win in the main 6 reel board will explode and more will drop down from above to replace them.

If a symbol in the carts is used, more symbols in carts will roll in from the right to replace them at the same time creating a dual reaction of cascades.

Free Spins: Find the word G.O.L.D (ie 4 or more scatters) across the 6 reels 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 carts and the amount of multipliers are unlimited allowing for some truly momentous wins.

Bonanza MegaWays: On every spin the number of symbols on each reel will change and so will the number of ways to win.

The maximum number of ways to win is an impressive 117,649, but expect more like a few thousands on each spin. All pays pay left to right for 3 or more of the same adjacent symbols.


  • High 10,000x stake max win
  • Cascading reels offer more wins
  • Free spins with increasing multipliers offer biggest wins
  • Good 96% RTP


  • Patience needed to trigger free spins
  • Graphics could be better

Bonanza Review Conclusion

One big let down of this Bonanza slot on mobile is the graphics. The game play and features and concept is good, but you don't truly feel immersed in the whole Wild West gold prospecting slot theme.

However, with up to 117,649 ways to win, those extra cart symbols above the four center reels and those potentially high paying free spins, this medium variance slot machine has plenty of charms.

It's an easy to play game, if a little confusing potentially for beginners, but the minimum bet of 0.20 per spin allows all types of slot players the chance to spin a few rounds.

If you like this Bonanza Megaways slot then it's worth taking a look at another of the Big Time Gaming slots the Queen of Riches slot.
