About Tangram
Turn, flip and fit seven coloured pieces into a silhouette on a lamplit workshop bench. Find your own covering: matching the outline matters, rather than copying a hidden arrangement.
How to play
- Goal
- Fill the silhouette with all seven pieces.
- How it ends
- No gaps or overlaps. Every covering counts.
- Record
- Your first unassisted time. Reloaded attempts are practice.
- Select a piece, then tap its destination, or drag it into place. Select a placed piece to move it again.
- Turn pieces in 45° steps. Flip the parallelogram to use its other side.
- Cover the whole silhouette with all seven pieces, leaving no gaps or overlaps. Any valid covering solves it.
- Undo and Redo revisit your arrangements. Restart clears the pieces but keeps the same puzzle and clock.
