The wild symbol is the glistening diamond and it can substitute for all the other symbols, except the scatter, to help and form winning combinations. Furthermore, it is the slot's most valuable symbol.
The scatter symbol is the slot's logo. Landing two or more of them anywhere on the reels awards a scatter payout and the symbol is also key to the free spins.
Six of the game's symbols, the bars and the sevens, will always appear in stacks and occupy two reel positions. This can be a great help in landing numerous wins on a single spin.
When three or more of the Gem Heat scatter symbols land anywhere on the reels the free spins game begins. The spins begin with a 2x multiplier and every two spins the multiplier increases by 1x. Furthermore, for the duration of the free spins a wild symbol is locked in place in the centre of the third reel to help you form as many wins as possible.
Gem Heat offers a huge top payout of 3,000x for landing five wild symbols along a payline. The gold bars can payout up to 1000x, the dollar sign can payout up to 600x and the horseshoe can payout up to 400. The scatter symbol also offers huge payouts of 100 times the total bet for that spin if five land anywhere on the reels.
