Alien Evolution UPUP Slot Rules Introduction
Winning Rules
In Alien Evolution UPUP, wins occur by matching 4 identical symbols adjacent to each other vertically or horizontally. The payout is determined by the number of winning symbols matched. Winning symbols are then removed and new symbols fill the grid. This process continues until no further winning combinations exist. Only groups of four or more adjacent, identical symbols count as a win. Groups of two matching symbols do not qualify.

Clearance Symbols
- The game prioritizes removal of clearance symbols. Once cleared and no more remain on screen, matching combinations are then calculated.
- Collecting 15 clearance symbols over Level 1 and Level 2 progresses the game to the next stage. Clearance symbol counts do not carry over.
- Exiting the game mid-progress is treated as forfeiting. Upon re-entry, players will start again from Level 1.
Reset Symbols
- Collecting 15 reset symbols at Level 3 will return the gameplay to Level 1.
Free Game
- Landing a free game symbol on the board triggers 15 free spins.
Multiplier Symbols
- During free games, whenever a multiplier symbol appears and wins are scored, the multiplier is added to the total multiplier.
- When another multiplier symbol appears and a win is made: win amount × total accumulated multiplier = final payout for that round.
