Bonus functions and unique mechanics
- The main feature of the slot — multi-level bonus game, activated by three or more scatters (Kettalkoatla emblem). When activated, the player receives 10 free spins and starts the journey from the first level.
- During free spins:
- An additional Wild symbol (green eye) appears, which is collected in a special counter.
- For every 2 collected Wilds, an upgrade occurs from one of the regular symbols to the highest paying one (statue of Kettalkoatla).
- After completing the current level, the player can advance to the next if they have collected enough Wilds. There are a total of 5 levels — and with each one, the potential win increases.
- New free spins are not reset, but improved symbols are retained throughout the entire bonus round.
There is no separate risk game or gambling in the slot.
Expert opinions and recommendations
