I taught our dog to play hide and seek. For the seeking part, I make him sit in the kitchen and wait while I hide with his toy. Then I yell his name and he has to come find me. For the hiding part, he will take his toy and hide it somewhere like under a couch cushion or under a bedsheet. Then he comes and finds me to go looking for it. If I get too close to finding it then he jumps in and snatches it.
