Logic Puzzles
(E?)(L?) http://www.johnpratt.com/items/puzzles/
- Optical Illusions. Some great optical illusions.
- The following are selections of my favorite puzzles, arranged by category. They contain only "best-of-class" type puzzles, meaning there are not many repeats of the same type and difficulty of puzzle. There are also no riddles, or trick answers. I never liked them.
- Logic Puzzles. These puzzles require no mathematics at all, but only straightforward thinking. They begin at elementary school level and get tougher.
- Math Puzzles. These puzzles some mathematics, but the first ones don't need much. They begin at elementary school level and get tougher.
- Science Puzzles. These puzzles require knowledge of at least high school physics.
- Genius Test. No one gets a perfect score on this test, but it can be a lot of fun at a party where most people score over half.
- Jacob's Missing Descendant - A logic puzzle which may be both the world's oldest as well as best puzzle!
