Be sure to choose one that will be challenging to you—no fewer than 500 pieces please!

Mundane as they may seem, jigsaw puzzles provide a good workout for your brain. Completing one requires you to heavily engage your visual processing system—scanning for target pieces, making fine distinctions about shapes and colors, mentally rotating pieces in your mind. It also engages the brain system controlling movement as you manipulate pieces in your hand and shift attention from the small piece to the “big picture.”
