TANGRAM

1Fill the shadow with seven pieces

Make the shadow's shape with the seven pieces. The shadow shows no lines between pieces: working out which piece goes where is the puzzle.

2The seven pieces

• ×2
• ×1
• ×2
• ×1
• ×1

Two big triangles, a middle one, two small ones, a square and a parallelogram. Together they make the square they were cut from.

3Three rules

1. Use all seven pieces
2. No overlapping, nothing sticking out
3. Turn and flip as you like: any way that fills it is right

4Controls

5Difficulty and medals

• ★★★★★Difficulty from ★1 to ★5: shapes with arms and corners are easier, compact ones harder
• Three medals: solve it, use no hints, beat the target time

7A tip

Place the two big triangles first. Once they sit in the widest parts of the shadow, the rest comes much more easily.
