Cool Jewels by Williams Interactive uses the new Exploding Pays game engine. This game looks a lot more like Candy Crush or Bejeweled than like a regular slot. The 6 x 6 array has no paylines as such and instead you must collect groups of 4 or more symbols. Winning symbols explode to make room for new symbols to drop down and each symbol that explodes increments the Pay Per Symbol meter by one slice (a step on the meter consists of 6-15 slices).
The game has 4 different types of wild (3 of which only appear on reels 2-5) – shocking wild, unstable wild, shattering wild and persisting wild. These are activated if they form part of a winning combination, and explode as described below.
A shocking wild explodes symbols along diagonal lines, a shattering wild explodes symbols horizontally and vertically and an unstable wild explodes adjacent symbols. Two different wilds next to each other activate extra features, with spaces in the area of influence of one of them getting a coloured watermark which causes them to explode, gives them a 10x multiplier or turns them all wild. Two of the same wilds next to each other create a persisting wild which explodes adjacent spaces but does not explode itself until it either reaches the bottom row or runs out of winning combinations. There’s also a 10x multiplier symbol.
Big wins result from chain reactions as these get the Pay Per Symbol meter (which is reset after every spin) up high. If this all sounds insanely complicated, that’s not surprising, because it IS very complicated, and we haven’t even got to the bonus round yet!
To trigger the free spins bonus round, explode 4 or more Cool Jewels bonus symbols in the course of a spin. This will award 8 free spins (higher numbers of bonus symbols exploded award more free spins and there is no upper limit). The free spins take place on a richer set of reels (which means a better chance of wild combos and of getting the Pay Per Symbol meter up high, for bigger wins).
