This game was a Christmas present for high-volatility slot fans in December 2016. It followed on from Starquest and is part of a trio of games that includes White Rabbit and Danger High Voltage that nails the BTG colors to the mast – Kings of the high volatility joy-ride!

Bonanza is available to play at all Big Time Gaming Casinos.

Bonanza is set in a gold mine with dixie-town music, but it’s the MegaWays™ reel set up that is eye-catching – the middle four of six reels have one extra symbol, and each of the six reels can have anything between two and seven symbols on it.

The number of ways to win changes accordingly and can reach as high as 117,649!

You will definitely find that this is a high volatility number, so be warned – the bonus round is where you need to head if you want to win big here.

Some Key Facts About Bonanza Slot

  • Bonanza pays out left to right on adjacent symbols to the tune of 117,649 winning combinations.
  • The game comes with four high paying gemstone symbols from the emerald green (2x for six in a payline) to the round purple stone (50x for six in a payline).
  • The lower value symbols are the cards 9 through to Ace.
  • Watch out for the mine carts at the top of the reels – they move left to right and add an extra symbol to each reel.
  • The game uses Rolling (dropping, avalanche, cascading) Reels. With each winning spin the winning symbols explode and are removed to be replaced with new ones. This continues until no winning lines are visible.
  • The Wild is a stick of dynamite – it replaces all others except the scatter.
  • The scatters are gold boxes with letters G, O, L and D on top. Four are needed to trigger the bonus round.
  • Bonanza can be played from 20p up to £500 per spin.

Bonanza – How It Works

Bonanza MegaWays™ bears all the classic hallmarks of the best Big Time Gaming slots – great graphics and animations and big, big volatility.

The mine backdrop is a cool setting for this slot, and you’ll enjoy watching the little cart move around the top of the reels and deliver extra symbols with each spin.

In the base game, just look out for extra wilds that can build decent wins for you, and also of course the Rolling Reels feature that keeps rolling on for consecutive wins.

Of course, like other BGT games, the big treasures are kept locked away in the bonus round.

Here’s what you need to do to access them.


You’ll need to land four of the scatters (gold boxes) to set off Free Spins, starting with 12. Every extra scatter above your base four gets you an EXTRA FIVE FREE SPINS.

Bonanza Slot Bonus Round













So before you even start the bonus round you can notch up a nice Free Spins bank.

The Rolling Reels Feature remain active during the bonus, but this time a multiplier is applied after each successive win. It starts at 1x and goes up by 1 with each new spin – and there is NO MAXIMUM.

Gold Bars Add More Free Spins – During the bonus round the carts above the reels might just stop with gold bars in them. When they do, add another 5 FREE SPINS for three in a cart, and 10 FREE SPINS for four in a cart.

So there you have it – a bonus round that can delivers big, big riches when the free spins and multipliers start adding up.
