The Seven Boards of Skill
China’s qiqiao ban — a puzzle craze since the 1800s

SEVEN PIECES

Two large triangles, one medium, two small, a square and a parallelogram. Every figure uses all seven — no overlaps, nothing left over.

DRAG, ROTATE, FLIP

Drag pieces onto the dark silhouette. Rotate in 45° steps; the parallelogram can also flip. Pieces click into place when they fit.

HOW TO PLAY
Tangram — the seven boards of skill

THE GOAL

Recreate the dark silhouette using all seven pieces. Every figure uses every piece exactly once, with no overlaps.

CONTROLS

Drag a piece to move it. Select a piece and press Rotate to turn it 45°. The parallelogram is the only piece that sometimes needs the Flip button — it has a left-handed and a right-handed form.

SNAPPING

When a piece is close to its correct spot in the correct orientation, it clicks into place and locks. Stuck? The Hint button flashes the outline of one missing piece.

THE HISTORY

Tangram emerged in China around 1800 and swept Europe and America within decades — Napoleon reputedly played it in exile. The name qiqiao ban means “seven boards of skill”, and thousands of published figures exist.

SOLVED!
The Square complete — 0 of 5 figures mastered.
