Stackdle

What Stackdle is

Stackdle is a daily physics-based stacking puzzle from Amountle. Each day brings one new set of 20 falling shapes, and every player receives the same sequence. Your job is to guide each piece onto the growing tower, rotating it as needed, then let it settle. Because the tower is simulated with real stability, an awkward placement can make the whole stack wobble or fall. You are allowed three falls before the attempt ends. The height that holds and remains standing counts as your score, and the tower must stay still for a moment for that height to register. Some daily sets ask you to build out past the edge or bridge a gap, so height alone is not always the only goal. If you want more reps, an endless practice mode supplies a steady stream of extra pieces.

How to play

Your objective is simple: keep stacking the provided shapes as high as possible without letting the tower topple. Move each shape over the stack, rotate it with the rotate handle, by scrolling, or with a two-finger twist on a phone, and drop it onto the tower. After the piece lands, wait for the tower to stop moving; once it stays still, that height counts. The run ends after three falls, so choose placements that give the tower a stable base. You can play the daily set or switch to practice mode for endless pieces.

Tips

1. In daily mode you only have three falls, so favor a steady landing spot over a risky placement that might add a little height.
2. Some daily shape sets are built around reaching past the edge or bridging a gap, so watch for pieces that can lock the tower together instead of just sitting on top.
3. Give the tower a moment to finish moving; the height counts only after it stays still, so a piece that is still settling should not be treated as final.
