Tangram

Arrange the seven classic tans to fill every outline perfectly, edge to edge, with nothing left over.

How to play

Each puzzle gives you a target silhouette. Drag, rotate and flip the seven geometric pieces until they cover the shape exactly, with no gaps and no overlaps. Pieces snap to a fine grid so precise fits lock cleanly into place.

• Drag a tan to reposition it
• Rotate pieces in 45-degree steps
• Flip the parallelogram (the only piece that flips)
• Overlapping or out-of-bounds pieces glow red until you fix them

Controls

• Desktop: drag with the mouse; press R or E to rotate, F to flip; Hint and Reset buttons available
• Phone & tablet: drag pieces with your finger; use on-screen rotate and flip buttons

Game modes

• Daily: one fresh silhouette to solve each day
• Practice: pick from a library of puzzles across difficulty levels

Tips & strategy

• Place the two large triangles first, since they eat the most area
• Work corners and straight edges of the silhouette before the interior
• If a piece won't fit, try flipping the parallelogram, the only one that mirrors
