Tangram

About the game

Tangram is a set of seven geometric pieces: five triangles, one square, and one parallelogram. Together they form a perfect square. Your goal is to use every piece to match the given outline—no overlaps, and no pieces left over or unused.

Controls

• Move: Drag a piece.
• Rotate: Tap a piece or use the rotate control.
• Flip: Some puzzles allow flipping; check the level for whether it is enabled.
• Reset: Start the level over if the board gets messy.

How to clear a level

1. Use all seven pieces.
2. Make sure pieces do not overlap.
3. Match the outer silhouette of the target.

Hit all three and the level is complete.

Tips

• Place the large triangles first, then fill gaps with the smaller pieces.
• Silhouette puzzles show only the outline, so try more than one arrangement.
• The parallelogram is easy to put the wrong way round—check it when you get stuck.
