About Stack

Stack is a one-touch skill game: a block slides back and forth above your tower. Press space or tap to drop it — anything that overlaps the layer below sticks, the rest crumbles away, and a complete miss ends the run. Every ten layers you climb a level and the block moves faster, so timing and reflexes decide how high the tower gets. Play it on desktop or mobile with no download and no signup. Everything runs on your device, and your best score and highest level stay right here.
