There are various sets that can be enjoyed on their own, but for maximum fun, get the PlayTab board (sold separately) that allows one to snap in up to six modules for a full sensory experience.

Each tile has a magnet on the back that sticks to the PlayTab board (sold separately) or can snap to a fridge.

There's a set of gears that spin together, textured buttons that squeak, colorful balls that roll through a maze, a dial that clicks from one to ten... They all magnetically snap onto the board any way you want. Or, you can just throw a few in the diaper bag, or even stick them to the fridge! The classic activity board becomes more versatile and more open-ended with PlayTab.
