Studies have shown that your brain needs exercise. But hard brain teasers and number puzzles not only aren't fun, they often don't give a complete brain workout. That's why we created the BrainReady BrainChallenge. You won't find any trivia, math, or logic puzzles here - just creative exercises that exercise your visualization skills, memory, vocabulary, and reasoning. We're not testing your knowledge, we're working your neurons. The only thing you need is your mind and a pencil. This description may be from another edition of this product.
