Duncan Color Shift Puzzle Ball
by Duncan Toys
Duncan The Original. World's #1. For more than 8 decades Duncan's performance and quality has been something you can depend on in a toy. Color Shift will challenge your mental skills while having fun! Probably the most unique Puzzle, 11 filled holes out of 12, mix up the inner color balls and try and solve to match the color ball with corresponding hole! Great with another player as you can mix up for them and see how quick they can solve!
