How to play

  1. Look at the shadow. All seven pieces fit inside it, with no gaps and no pieces on top of each other.
  2. Slide, turn, flip. Drag a piece. Tap it, then press Turn or Flip, or tap it twice quickly to turn it. Close is good enough: it clicks into place.
  3. Start big. The two big triangles are the hardest to fit, so place them first. Stuck? Hint puts one piece in for you.
Your seven pieces: two big triangles, one middle triangle, two small triangles, a square and a parallelogram. Together they make this square.
