Rainbow Puzzle Ball

Give your hands a colorful matching challenge with this rainbow puzzle ball. Small colored balls sit inside a round shell with colored rings around its openings, leaving one space free so the pieces can move. Push a ball inward and across to the empty opening, then continue working until the colors line up with their matching rings. The rounded format changes the familiar sliding-puzzle idea into something you can turn and inspect from every side. At approximately 7cm across, the ball is easy to keep on a desk or take out for a short puzzle break. Its contrasting colors make the goal immediately understandable, while the shifting positions give you a fresh sequence to solve after each scramble. Try planning several moves ahead, or simply explore the mechanism one move at a time. The puzzle needs no screen, cards or separate playing board, keeping the activity contained in one object. It is an appealing little challenge for anyone who enjoys hands-on puzzles with a clear visual finish.
