Do you crave brainteasers? Do your students delight in them? (Many of my students do!) Terry Stickels is a world-renowned puzzlemaster who has published several diabolical books of challenges and authored weekly puzzle columns in many newspapers. You can find out more about him here. One type of “stickler” that has made him famous is called, “Frame Games,” which are like rebus puzzles, but placement and size of the text give clues as well. For example, the picture below would translate as, “I understand.”
On the Terry Stickels website you can find many free brainteasers, including a series of “Frame Games.” There are coin puzzles, variations on sudoku, and several other types of challenges. Some can be downloaded in tremendous zip files, and others are meant to played online. Whenever you are looking for a way to pass the time, (such as during the summer break) and still exercise your brain, this is a resource you should definitely consider!
