Paper Fold

How to play

A square sheet of grid paper is folded one to three times — watch each crease and which way the flap goes. Then a hole is punched through every layer of the folded paper. The sheet goes back to flat and you tap every cell where a hole will appear once it is unfolded, then press Check. Each correct answer adds one to your streak, and the puzzles grow harder: more folds, bigger grids and folds that are not exactly in half. One wrong answer ends the run and shows the paper unfolding so you can see where the holes really were.

Tips

• Each fold doubles the layers under the punch — but only where the flap actually covers the paper.
• Holes are mirror images across each crease line. Unfold in your head one crease at a time, starting with the last fold.
• When a fold is not in half, cells beyond the flap's reach get only one hole.
• Use Replay as often as you like before checking your answer.
