Jack Frost is pitted against his brother Harold Heat in a battle to control the weather. With Jack Frost in control the slot is a winter wonderland of frosty icons – ski goggles, skates, winter hats, gifts, shiny ornaments, candy canes, and a Frozen Wild. When Harold Heat shows up the snow melts away and becomes a tropical paradise with icons such as sunglasses, sandals, sun caps, coconut drinks, bananas, and a Red-Hot Wild. Jack and Harold's elf-like minions make an appearance as well. The card suits complete the icons, appearing in both cold and hot themes.
