Perfect Stack

Drop 10 moving blocks to build a tower in a free one-button stacking game. Trim missed edges, chain perfect drops and beat your saved best score.

Time each drop as a moving block crosses the tower. Any overhanging edge is cut away, leaving a narrower landing for the next, faster block. Miss the tower completely and the run ends; place all 10 blocks to finish. A centered perfect drop preserves the full width and builds a score combo, while partial overlaps score according to their precision. Play with one tap, click or press of the Space bar, retry instantly and beat the best score saved in this browser when storage is available.

How to play

Space / click / tap

Watch the moving block, then tap the playfield, click or press Space to drop it onto the tower.

Land at least part of the block on the layer below. Any overhanging section falls away, so the next block has a smaller target.

Place all 10 blocks to complete the tower. A complete miss ends the run, and Stack again starts a fresh attempt.

Tips

Center a block closely enough for a perfect placement. Perfect drops keep the tower at its current width and build a higher-scoring combo.

The blocks move faster as the tower rises. Use the same visual landmark to judge the center instead of chasing the moving edge.

A partial overlap keeps the run alive. Protect the remaining width when a perfect drop is risky.

Can I play Perfect Stack with one button?

Yes. Every drop uses the same action: tap, click or press Space. Press R or use Stack again to restart after a completed or missed tower.

How do perfect drops and scoring work?

A centered perfect drop preserves the whole block and starts or extends a combo. Partial overlaps trim the block and award points based on how much landed. A complete miss ends the attempt.

Does Perfect Stack save my best score?

Yes. Your highest score stays in this browser when storage is available. Clearing site data removes it; no account or download is required.
