Features

Build, then shake

Drag wooden beams between joints under a small budget, then press Shake. If the tower falls, or sways so much that the matcha slops over the rim, you lose.

Everyday shakers

A washing machine on its spin cycle, a cat that leaps onto the table, and the last train rattling past the window. Each one shakes in its own way.

Every fail tells you why

The result card names the cause, like “0.1 s after the cat landed, a 1st-floor brace buckled”, and the beam that broke first blinks when you go back to fix it.

Real structural ideas

Triangles beat boxes. A hit is not a steady shake. A tower that sways in time with the train can spill without a crack. Steel is strong, heavy and expensive.

Today's Puzzle

A new site and shake every day, the same for everyone. Build it for less than our own build and keep your streak going.

Clips to share

Every shake is recorded as a 9:16 clip with the level and your cost. Save it or share it straight from the result card.

Chapter 1 (washing machine, 15 levels), Chapter 2 (cat, 9 levels) and Today's Puzzle are free. Pro (one-time) adds Chapter 3 (the last train, 9 levels with steel) and every past daily puzzle. Founder adds a kintsugi bowl and a silk cloth on top of Pro.
