stacz: Falling Block Puzzle

Stack falling blocks of the same color to charge them, then land another matching block on top to clear the stack. Reach each round’s point target before your blocks reach the top.

Swipe to move each falling piece and tap to rotate it. Pieces can be black, white or a mix of both, so line up their colors with the blocks below. Charged blocks glow gold: keep them within reach of your next matching piece.

A well-placed piece can clear several vertical stacks at once. Blocks above the gaps fall into place and can trigger further clears. Keep clearing with consecutive pieces to raise your point multiplier; a piece that clears nothing ends the streak.

Hit the round target and the whole board clears. The next round starts with a higher point target, while your total score carries on.

Choose Easy, Normal or Hard. On Easy, pieces fall more slowly and the floor stays put. Normal and Hard bring faster falls and new rows from below that push your stacks upward.

Your best score and highest round are recorded separately for each difficulty.

How many rounds can you complete before you run out of room?
