Yes we play the hiding under the covers with Caesar and he digs like crazy!
Also i will stand at the top of the stairs behind the wall and he will be on the bed then get off hte bed and walk towards me I jump out at him he runs like a little mad man to hte bed and we do it again. I hide behind the wall up on the stairs, behind the bathroom or bed room door, and sometimes on the other side of the bed on the floor.
My husband plays with him a lot by having his hand under the cover and Caesar will attack/pounce/and bite at the hand under the cover.
And of course, he loves the chase game. Where we will just lunge towards him and he will take off running and then come back for more.
