Tangram is a shape puzzle with seven flat pieces and one rule: fill the silhouette exactly, with every piece and no overlaps. It looks simple, but the same seven pieces can make hundreds of figures. These tips will help you see where each piece belongs.
The seven pieces
Every figure uses the same set: two large triangles, one medium triangle, two small triangles, a square and a parallelogram. Together they cover 8 square units, where the square piece is 1. The large triangles take up half the area between them, so they matter most.
Moving, turning and flipping
Drag a piece to move it, and tap it to turn it an eighth of a turn clockwise.
The Flip button mirrors the parallelogram. It is the only piece that changes shape when flipped, so if it will not fit at any angle, flip it.
Drop a piece close to where it fits and it snaps into place corner to corner, so you do not need to be exact.
On a computer, Tab picks a piece, R or Space turns it, the arrow keys move it and F flips.
Start with the large triangles
Look for the biggest areas of the silhouette first: wide triangles, 2 by 2 blocks and long diagonal edges. The two large triangles usually go there, and there are only a few places they can fit. Once they are placed, the smaller pieces have far fewer options.
Read the corners and edges
A sharp 45° point in the outline is almost always the tip of a triangle.
A square corner can be the square piece, the right-angle corner of a triangle, or two pieces meeting.
Slanted edges that run parallel, a short step apart, often belong to the parallelogram.
Leave the two small triangles for last: they fill the leftover gaps.
Levels, hints and times
There are 33 figures, from arrows and houses to animals, letters and numbers, ending with convex shapes like the rectangle and the classic square. Solving one unlocks the next. Any arrangement that fills the figure counts, so your answer does not have to match a stored one.
If you are stuck, Hint outlines where one more piece goes, biggest first. The clock starts when you first touch a piece and your best time for each figure is saved, so try again without hints for a faster time.
