Stack the aliens on each other correctly and prevent them from falling.
How to play Stack PileUP
The opening minute doubles as the tutorial. Load the game above and it fills the player in portrait. On a phone you can play one-handed; on desktop the frame stays centred so nothing is cropped. If a round goes badly, restart — attempts are cheap and it is usually the fastest way to improve.
