Alien Evolution UPUP Slot Gameplay Guide
Alien Evolution Slot-Winning Rules
In Alien Evolution UPUP, matching symbols must be adjacent (up, down, left, right) to win. Payouts are based on the number of winning symbols. After wins, symbols eliminate and cascade until no more combinations exist. Minimum 4 adjacent matching symbols required - 2 symbols won't trigger payouts. As shown below:

Alien Evolution Slot-Cascade Symbols
- The game prioritizes eliminating cascade symbols first. Payline calculations begin only after the grid is filled and no cascade symbols remain.
- When 15 cascade symbols accumulate across layers 1 and 2, the game advances to the next layer. Cascade symbols cannot carry over between layers.
- Leaving mid-game forfeits progress. Re-entering starts from layer 1.
Alien Evolution Slot-Reset Symbols
- When 15 reset symbols accumulate in layer 3, the game returns to layer 1.
Alien Evolution Slot-Free Games
- When free game symbols appear on the grid, players enter 15 rounds of Free Games.
Alien Evolution Slot-Multiplier Symbols
- In Free Games, when multiplier symbols appear and win, the added multipliers accumulate to the total multiplier.
- When new multiplier symbols appear and win, grid winnings x accumulated total multiplier = final round winnings.
