As colourful as the rainbow! With this shape-fitting and stacking game, the goal is to stack identical shapes on top of each other by size so that the colours of the rainbow are formed in the correct order. Stacking, inserting, and sorting playfully teach children about shapes, colours, and sizes while training fine motor skills and hand-eye coordination. The movable pins add to the safety! Absolutely endless stacking and sorting possibilities. Who can complete the rainbow?
