Play Stacker free online! Stack moving blocks precisely to build the highest tower. A skill-based arcade game that tests your timing.

How to Play

• The block snaps over the previous one — only the overlapping part stays.
• The narrower your stack gets, the harder it becomes.
• Reach the top to win the level!

Tips & Tricks to Stack Higher

• Watch the rhythm of the block's movement, not just its position — time your tap to the beat of its swing.
• Tap slightly early — account for your reaction time delay. If you wait until it looks perfect, you'll be too late.
• Stay calm and breathe — nervousness kills accuracy. Each layer is just one tap.
• Perfect alignment matters more early on — even a tiny misalignment in the first 5 layers compounds into a very narrow stack later.
• Focus on the edges — watch where the block's sides line up with the stack below rather than the center.

Why Play Stacker?
