Bomb Bonanza Bonus Features

A quick look at the paytable will soon reveal that the game has two bonus features. One constitutes expanding wilds and the other – the free spinsbonus round with a progressive golden nugget feature.


Bombs are wild and can substitute for all symbols except scatters when they hit the reels as part of a winning combination. Each time a wild lands in the base game or free spins, it also has a potential to expand across positions that surround it. As it expands, the existing symbols will turn into wilds creating wild squares of up to 5×5 in size. The only downside of these expanding wilds is that some of them might spread outside the grid.


The scattered free spins triggers can appear on reels 1, 3 and 5 and trigger the bonus round when 3 show up on the designated reels at the same time.

Free Spins

A new symbol, gold nugget, is introduced when you trigger 6free spins with 3 scatters. Each time it lands, it will explode, triggering a mini avalanche. A new symbol will fall down in its position to fill the gap while the exploded nugget will be collected in the special metre positioned to the right of the reels. Containing a progressive multi-level feature, the free spins round starts at level 1 with 1×1 expanding wilds. Charging the metre with 3 to 5 gold nuggets increases the wild size pattern and moves you up a level, like so:

  • Level 2 – 5 nuggets award +4 free spins + all wilds expand in a 2×2 pattern.
  • Level 3 – 5 nuggets award +2 free spins + all wilds expand in a 3×3 pattern.
  • Level 4 – 5 nuggets award +2 free spins + all wilds expand in a 4×4 pattern.
  • Level 5 – 3 nuggets award +1 free spin + all wilds expand in a 5×5 pattern.
