Tangram — 82 silhouette puzzles, plus a printable pack
Tangram is now live — 82 silhouette puzzles built from the classic 7-piece set.
How it works:
- Drag a piece onto the board, tap to rotate it 45°, flip the parallelogram with its mirror badge.
- Pieces click into place when the position and angle are right. The tray shows a ✓ for every locked piece, so "how many are really done" is always visible.
- A beginner ramp: the first levels use 3-4 pieces, and the full 7-piece classics start at level 9. Progress saves locally — close the tab, come back tomorrow, same level.
The deliberate design choice: no timer and no hints that solve it for the child. A wrong placement wobbles and stays put; figuring out why it didn't fit is the actual exercise.
Best for ages 5-7. Builds spatial reasoning — the why is in Tangram for kids: a quiet spatial workout.
