How the Game Plays

Polar Heatwave transports players to a frozen Arctic landscape where a group of animals is preparing for a surprising shift in weather. The game features a 5x3 grid with 10 fixed paylines, where winning combinations are formed by matching symbols like polar bears, seals, and seagulls from the leftmost reel. The base game is visually defined by ice-encased card suits and chilled creatures, with a Penguin Wild symbol appearing on the middle reel to assist in completing winning lines.

Free Spins Explained

The core of the action begins when three or more Sun Bonus symbols land on the reels, triggering up to 20 free spins. During this round, a thermometer mechanic tracks every Sun symbol that appears. For every four symbols collected, the temperature rises, unlocking one of five progressive levels. Each new level rewards players with additional free spins and upgrades the gameplay with increasingly powerful features.

Thermometer Features Explained

As the thermometer moves from a bone-chilling -20°C toward a thawing 0°C, the Arctic environment changes and the rewards intensify. Progression through the levels can unlock up to three full Sticky Wild Reels and a 2x win multiplier. Reaching the fourth level introduces a "win both ways" mechanic, allowing combinations to pay from both left-to-right and right-to-left. By the time the temperature reaches zero, the ice has melted, and the potential for massive combos is at its peak.
