Challenge your mental skills while having loads of fun!
A slightly smaller, beginner model to its larger sibling, Duncan's Junior Colour Shift Puzzle Ball can be solved by matching all of the coloured balls with their corresponding coloured rings.
There are 8 holes with only 7 filled with a coloured ball. To start, re-arrange all colours by pressing a ball down and shift it to a nearby hole. Utilize the empty hole to maneuver balls around to find their matching hole. Once all balls match, the puzzle is solved!
