Mensa Math and Logic Puzzles

Join the ranks of the geniuses, and leave behind the merely brilliant! Try to figure out 20 tough types of puzzles like the ones found at international puzzle competitions. These are puzzles that require no verbal skills to solve; you just need your logical brain. How hard can they be? Simple arithmetic and a sharp pencil (with a full eraser) are all you need, plus paying close, close attention. Start by following twisting paths made by worms crawling across triangular grids. Then forecast weather patterns by detecting rain cloud patterns in a numbered diagram. Find lost fleets of ships in grids where only a few different shapes are visible. Rearrange dominoes according to a diagram (problem is, the edges of the tiles have been removed). More fun awaits you with hex loops, skyscrapers, lighthouses, and other suddenly fiendish objects.
