These puzzles are challenging and keep your mind alert and keen.  I never realized that exercising the brain could be just as important as keeping your other muscle groups in shape.  I buy every Grabarchuk puzzle book they come out with, and I am NEVER disappointed!  Colorful and elaborate, I think these books would be a real treat for anyone who tries them.
