"Which English word has all six vowels in alphabetical order?" "What dries and dries and keeps getter wetter?" "How much dirt is in a hole four feet by two feet?"

The Grey Labyrinth is a playground of mental calisthenics for curious minds. Visually stunning, it was created to showcase the talents of a group of graphic-designing puzzle enthusiasts. Current problems are posted without their solutions. About once a month, a new question is posed along with the answer to the previous puzzle. The authors encourage feedback from readers who disagree with their solutions, or those who propose alternative answers. This month's puzzler digresses from their usual format as it is a collection of twelve mini-puzzlers ending with "Name the seven wonders of the ancient world."
The Mind Breakers want to "brighten up your grey brain-cells" with the best in puzzles and riddles. Each of their listed puzzles is rated for "coolness" and complexity on a scale of one to four. Call me uncool, but I couldn't tell what made one riddle cooler than another. Temperature aside, navigation around the site is simple, and answers are supplied. Be warned, however, some of the riddles have trick answers.
Not another page of riddles, but this site is so much fun I had to include it. When your mind has melted from too many puzzles, don't quit, fight back! Create your own puzzles to share with friends, family and students. Mazes in all shapes and sizes, word searches of varying complexity, number blocks and math squares are among the choices. Input your parameters, and press "Create." Your ready-to-print puzzle is created in seconds and you are granted permission to use it as long as you credit the Puzzlemaker Web site.
Welcome to the Ultimate Puzzle Site, where three Dutch students "guarantee that all puzzles and riddles on our site are interesting."
