Cool Jewels Overview

Cool Jewels is like match 3 games Bejeweled and Candy Crush Saga, only instead of matching three similar things you match four, and it all takes place on glittering slots reels. Because wins are removed from the board, making room for more jewels to come cascading down, the wins can just keep on coming. Might you be the one to win the $250,000 jackpot?

Playing Cool Jewels Online


Cool Jewels slot game has six reels and a match 4 win system. This means that wins can appear anywhere on the board. If four symbols are connected to each other vertically or horizontally, you could win. The lucrative wilds push the game to another level.

When you win, the symbols work to boost your multiplier gauge on the left of the reels. The more you wager, the higher your multiplier can get. Plus, each win is removed from the board, letting more jewels and potentially more wins cascade.


The symbols on the reels of Cool Jewels all look like sparkling gemstones. Mainly you'll be concerned with matching up the colors to make groups of four, but the exciting stuff happens with the wilds. These can work as bombs that spread wins across the board, and when they combine, the wins are truly lucrative.

There are also wild symbols, which can stand in for any other symbol except the special symbols. Special Aftershock symbols serve as multipliers, with double multipliers appearing on the first and third reels with a triple multiplier on the middle reel.

Bonus Games

When you match four or more Cool Jewels reel icons, you trigger the free spin bonus round. Don't worry about getting them all to appear at once – there’s a gauge on the right side of the screen. If you activate a Cool Jewel icon, for example, with a wild, the gauge fills. If cascading wilds bring you more Cool Jewel matches, they add to the gauge to trigger the bonus.

In order to activate the free spins, you'll land a decent win which triggered the Cool Jewels icons. That win determines your multiplier, making your wins during the bonus round even more lucrative. You could easily walk away from a small bonus with 40-50x your original bet.
