QFold Puzzles
The QFold puzzle website contains puzzles that are meant to be printed and solved with a pencil.
The puzzles are beautiful symmetrical designs that contain 20 hidden asymmetrical elements. To solve the puzzle, you identify these 20 elements of the puzzle and count the number of instances of each class of asymmetry (this is explained in a sample puzzle). This information is then used to identify a secret word or phrase.
The puzzles are free.
