WMS developers keep on surprising their fans with amazing slots that stand out from their peers in overall design and the set of features. Cool Jewels looks like a ‘match 3’ game with gems of different shapes and colors that a player must swap and match to win. In this slot, symbols are arranged on a 6×6 grid, and there are 8 regular symbols, 3 wilds and a few feature icons. A total bet per round varies from $0.5 to $200, thus, the slot will appeal to all kinds of players, both low-rollers and high-rollers alike.

Winning combinations are created by 4 or more identical symbols that border each other vertically and/or horizontally. These matching symbols explode and disappear, and new symbols then fall from above, filling all the empty spaces. To the left of the reels, there is the Pay Per Symbol Meter that indicates the current award for each symbol that has been destroyed. As symbols in paying combinations explode, the value in the Meter goes up, and you earn an increasingly higher award for every subsequent combination.

There are three wild symbols that act like bombs eliminating regular symbols in different explosion patterns. Unstable Wild will blow up all symbols placed on neighboring cells. Shattering Wild will destroy all symbols on the same row and column the wild is on, and Shocking Wild will explode all the symbols in a diagonal pattern. Any two wilds occurring as part of a single winning combination modify each other and produce a synergistic effect, increasing effectiveness of each other.

Bonus symbols (Cool Jewels Logo) destroyed during the game trigger a free spin feature, and the exact number of free spins you get is determined by the number of Bonus symbols collected. You may earn 8 to 20 free games with the chance to retrigger the feature under the same conditions.
