Stack

Stack is an arcade skill game where players stack moving blocks to build the highest tower possible. The challenge lies in timing your clicks precisely as the blocks move faster and become harder to align.

The increasing speed and shrinking block size ramp up the difficulty, making the game engaging and requiring quick reflexes. This progression tests players’ focus and coordination through increasingly intense rounds.

Keys & controls

Mouse click or tap: drop block

How Stack works

Players must click or tap to drop moving blocks so they align perfectly on the previous one. Misaligned portions are removed, reducing the size of the next block, which increases difficulty. The game ends when a block misses the tower completely. The goal is to stack as many blocks as possible to build the tallest tower.

Strategy tips

Focus on timing your click precisely as the block aligns with the tower.
Try to keep your blocks centered to avoid losing portions and making the tower unstable.
Keep calm despite increasing speed to improve your stacking accuracy.
