Seven-piece puzzles

Usage examples of tangrams.

This is not the case with Tangrams, a recreation that appears to be at least four thousand years old, that has apparently never been dormant, and that has not been altered or "improved upon" since the legendary Chinaman Tan first cut out the seven pieces shown in Diagram I.

This gentleman, it is said, records that there were originally seven books of Tangrams, compiled in China two thousand years before the Christian era.

If you place your Tangrams together on white paper so that they do not quite touch one another, in some cases the effect is improved by the white lines.
