A jigsaw puzzle with square pieces
Patchwork Puzzle is a picture puzzle like 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.
No pieces in correct location: -1 points
One piece in correct location: 2 points
Two pieces in correct location: 8 points
