These puzzles are not your average mini brain teasers. Every puzzle requires a different set of problem-solving skills, so figuring one out won't make it any easier to solve the next. They are incredibly fun and make great little gifts. Each box has a further nine matchbox challenges written onto the sides of the matchbox, providing hours of extra fun.
