Scientific Games subsidiary Williams Interactive has announced the release of its Cool Jewels game, the first online slot to use its innovative Exploding Pays game engine.

The company said that Cool Jewels is the first slot theme to launch simultaneously from Williams Interactive and WMS Gaming for play in-casino, online, and in social gaming, and “maximizes the opportunity” for casinos to benefit from the ongoing convergence of online and in-casino entertainment.

The game features no paylines or symbol hierarchy. Instead, the same symbol appearing in groups of four or more is a win, triggering a Cascading Reels style game play for additional chances to win on the same bet.

In addition, distinct WILD symbols appearing in a winning combination will give incremental wins, or land adjacently to create special WILD combinations for the chance at large consecutive wins.

Robin Littleworth, Williams Interactive’s senior director game development, said: “Cool Jewels introduces amazing new player-focused game mechanics that appeal to all player motivations.

“Using our Exploding Pays game engine, aligning four or more symbols will trigger explosions, giving players the chance to blast their way to big wins and free spins. Cool Jewels offers a compelling game experience unlike anything currently available to online slot fans.”

Cool Jewels is immediately available for European gaming operators integrated with the Williams Interactive Remote Game Server.
