here is a good game for testing memory and touch.
Blind man’s touch.
You need 12 household objects and a blindfold. Show your child 12 objects, then blindfold your child, and pass then 4 objects to feel then hide the objects back with the others and have your child find the 4 objects from the pile still blindfolded.
Another suggestion could be, getting a group of securely blindfolded children to sit in a circle while you place a big object in the middle, they need to feel the object and agree on what it is, and what it is used for
