The puzzles are marvelous, though many are a bit hard to understand -- often the author starts talking about a group of puzzles without explaining what the puzzle is. You may also have to work your way through some other random thoughts by the author; however, the puzzles on the page are worth sifting through the page to find them. Puzzles are listed in order of being added to the site, it may be easier to find items by looking on the right-hand side of the page and following the links listed under "Math Games". Activities are listed here by title without any explanation or picture, it would have been easier if they were in alphabetical order; however, this is still easier to find than scrolling through the long page of activities.
