The Wheels of Flame bonus feature consists of three levels: green, blue, and red. Each level is triggered by landing 3, 4, or 5 Flame symbols in a row, respectively. The potential rewards increase as players progress to higher-level wheels. For example, the green wheel offers up to 8 free spins, while the red wheel can award up to 50 free spins. Similarly, the maximum cash prize on the green wheel is 30x the bet, while the red wheel offers up to 500x the bet. This tiered system keeps players engaged and motivated to trigger higher-level wheels for greater rewards.
