BlockStack slides a block horizontally above your tower in an endless stacking challenge. Tap to lock its landing spot and stack it for points. Too much overhang can collapse the tower and end the run. Blocks keep coming endlessly, and higher stacks leave less room for error. Wait for solid overlap, place cleanly, and recover after near misses. Careful timing under rising slide speed decides how tall each endless tower can grow.
Tap to place sliding blocks and stack them. Imbalance ends the run.
