There are 3 bonus features in Cool Jewels – cascading symbols, wild symbols and free spins.
There are 3 wild symbols in Cool Jewels. There is a green shocking wild, pink exploding wild and blue blasting wild. Each of these wild symbols will become active if they are part of a winning combo.
The shocking wild will remove any symbols that are diagonally from it, the blasting wild will remove all symbols vertically and horizontally from it and the exploding wild gets rid of all symbols surrounding it. If there are two wilds next to each other during a winning combo, there are even bigger wins to be had. If there are 2 matching wilds in a combo, they will be locked and will stay active throughout each of the cascades until the symbols hit the bottom.
One of the biggest features in Cool Jewels is the cascading symbols feature. When there is a winning combination of 4 or more symbols, these will be removed and replaced by new symbols that can potentially form even more winning combinations and award big cash prizes.
Finally, we have the free spins bonus round. Four of the game logo symbols will trigger the free spins bonus round and while you usually have to get symbols in a winning combo to trigger features, in this game, they need to be destroyed by the wild symbols. 4 game logo symbols award 8 free spins, 5 awards 10 free spins, 6 awards 15 free spins and 7 awards 20 free spins. Each time you get another bonus symbol, you will be awarded another 5 free spins.
