The combination of expanding and increasing wilds, layered with multipliers and re-spins, creates moments where a single spin can snowball into a substantial result. This synergy is central to reaching the game’s headline reward.
Gameplay and Betting
The reels run on a 5×3 grid with 40 fixed paylines, offering an approachable layout for both newcomers and seasoned players. The betting range spans from 0.2 to 240 per spin, giving plenty of flexibility for testing different stake levels in the demo.
- RTP: 96.5%
- Volatility: Very High
- Maximum win: up to 10,000x the bet
- Bonus buy: Not available
With very high volatility, wins may arrive less frequently but carry greater potential when the features align.
