Gamblers who are keen on BAR symbols will be in the paradise at Gem Heat, as there are double bars, triple bars and gold bar symbols. Apart from the key BAR playing symbols, you will play with 7s and sparkling gems. Specific game symbols may appear as stacked, as you can see they occupy two rows on the reels. Those stacked symbols can be among the single, double or triple BARs, and so are the 7s. The wild symbol will replace any of the key symbols except for the scatter. Have in mind that when you get the Gem Heat symbol wherever on three or more reels, you can play the Free Games feature and will win 10 free spins.
