Patchwork Puzzle is a tile puzzle similar to a jigsaw puzzle but with square pieces. A picture is broken into squares that are then jumbled. Select two squares to switch their positions. Continue until the puzzle is solved.

Points are scored for the number of pieces moved to their correct position. Puzzles with more pieces are easier but you cannot score as many points.

Scoring:

No pieces in correct location: -1 points

One piece in correct location: 2 points

Two pieces in correct location: 8 points
