Jack Frost by Rival Gaming is a five-reel, 25-payline slot with a winter and tropical theme built around the rivalry between Jack Frost and Harold Heat. The game uses a cascading Drop Feature, where winning symbols are removed and new symbols fall into place, creating the chance for additional wins within the same spin sequence. The reported RTP is 94.26%.
The symbol set changes with the theme on screen. Winter images include ski goggles, skates, hats, gifts, ornaments and candy canes, while the warmer sequence features sunglasses, sandals, coconut drinks and bananas. A Wild symbol is shown in the interface, and the paytable also refers to Frozen Wild and Red-Hot Wild symbols.
Bonus play is triggered in two ways: three or more Harold Heat icons start the Free Spin Round, where wilds become Flaming Sticky Wilds, while three or more Jack Frost icons open the Ice Block Bonus Round, in which players melt ice blocks for coins or free spins. This demo version can be used to play for free and practice before playing for real money.
