All of the titles can be used independently or in conjunction with each other. A brain assessment quiz is included in each volume to see which side of the brain (right or left) is more dominant and which side needs to be strengthened. Each volume contains puzzles that enhance left brain skills with verbal, logic, and linear problem solving as well as the right brain skills in visual perception, spatial relationships, and creative problem solving. Finally, whole brain puzzles provide readers with intuitive-thinking exercises that test the skills of the right and left brain combined. The fun way to keep your brain lively and fit!
