Welcome to Mathematical Recreations

Sudoku of the Day. This site is a repository for interesting mathematical diversions. I'll add a new item each month (or so)—something more involved than a simple puzzle. There are now sixteen topics in this site and they are very diverse. I try to choose "real" problems from everyday life. Contributions are welcome (both new problems and solutions to problems that I post). We recently purchased a game called Spot it! One picture will be found on both cards. Please send responses to.
