Play Stack 3D Online — Free 🏗️
Stack 3D is the satisfying tower-building arcade game, rendered in real 3D. A block slides back and forth — drop it on the tower, and any overhang is sliced away. The more perfect your timing, the bigger your blocks stay.

How to play Stack 3D
- Tap, click, or press Space to drop the sliding block
- Overhang gets sliced off — the tower shrinks with sloppy drops
- Perfect drops keep the block full-size
- The tower speed rises as you climb — height is your score
