Stack — Free Online Tower Stacking Game

A block slides back and forth — tap to drop it on the stack below. Only the overlapping portion lands; the rest falls away. Build the tallest, most precise tower you can. Free, no download, instant play.

How to play

Watch the sliding block and tap at the moment it aligns with the stack below. The overlapping area becomes your new platform — the overhang breaks off and is lost. Each layer is narrower than the last if your timing is off. The game ends when the platform becomes too thin to continue.

Tips

Focus on the edge of the platform, not the center. A near-perfect tap is better than waiting for a perfect moment and overtapping. As the tower grows taller and the platforms shrink, the margin for error decreases — switch to controlled, deliberate taps rather than trying to react faster.
