Challenge Your Brain Math & Logic Puzzles (Mensa)

Challenge Your Brain Math & Logic Puzzles (Mensa) Review

Give your brain a workout on the type of brainteasers that challenge the best solvers at the World Puzzle Championships. They're tough, but fun, and the feeling of satisfaction you get when you succeed is simply unbeatable. Some of the puzzles are oldies but goodies, like battleships--and its many variants--where you search for a fleet hidden within a grid.

From Snaky Tiles to Spiral Galaxies, these Mensa-level conundrums will get your mind in shape.
