Stave Puzzles specializes in two types of puzzles: teasers and tricks. Teasers have extra-challenging design features, such as confusing colors, repeating shapes, and empty spaces in which nothing fits. In tricks, some pieces will fit into two different places, leading you to (mistakenly) believe you're on the right track.
Think you're up to the challenge?
