"aha! Insight' challenges the reader's reasoning power and intuition while encouraging the development of "aha! reactions": those sudden, creative leaps of the mind leading to short, elegant solutions to seemingly impossible problems. A confounding collection of brain-twisters in six categories - combinatorial, geometric, numerical, logical procedural and verbal- this book contains puzzles to first baffle and then delight both problem-solving addicts and novices alike.
