About Alien Stack
I went in expecting a throwaway minute with Alien Stack and ended up chasing my high score for ten. Each piece you add shifts the center of gravity, so you are constantly reading the lean and adjusting. One tip from a few runs in: stack as high as you can — don't miss. Anyone who enjoys a quick skill challenge over a sprawling epic will feel right at home. Like everything on PlayNova, it is free to play and runs straight in the browser with nothing to install.
🎮 How to Play
- Tap / Click to drop the sliding block
- Land it perfectly on top for a PERFECT bonus!
- The overhanging part gets cut off each time
- Blocks get faster as you stack higher!
- Stack as high as you can — don't miss!
Tip: on a phone, tap the screen; on a computer you can usually use your mouse, the spacebar or the arrow keys.
