First of all, the Polar Heatwave slot is about winter and cold lands inhabited by penguins, seals, and other creatures. Yet, as it’s a Heatwave, this means that summer can come to this land, bringing the sunshine and hot trends to the screen. The higher the temperature during the base game, the warmer it becomes. Animals change their clothes, while additional features are added as bonuses. Of course, it couldn’t go without the nice music and pleasant design that makes the background and buttons to navigate covered with ice and snow.

Polar Heatwave features a 5x3 grid-based in the sea among icebergs. Its symbols have 2 variations, which are designed for cold and hot modes. There are 10 lines in the basic game, and during free spins (from the 4th level), these lines pay both ways. Regular symbols are frozen card suits and several animals, including birds, seals, and polar bears. Cute penguins are Wilds that can land on the middle 3 reels during the base game. The sun that is bound to make the game hot is a bonus symbol that is in charge of free spins.
