Wilds

- Higher levels award bonus multipliers of 15-200 times the base wager. Each progressive increase leads to enhanced maximum payouts. The highest-rewarding Reel mode rewards a staggering 150,000 credits per line.
Reaching higher tiered combinations can trigger even more significant wins:
- Double (12×30)
- Triple (20×45)
- Wheel mode : By collecting Wheel symbols in consecutive order on reels two through six during any spin, the free spins wheel is activated. Players then select a number between one and seven.
