Birthday party and boys

This coming up wednesday, im having a birthday party for all my friends to hangout and have a good time. Im inviting my crush. I want to get him on my team, for games, and other things to get closer to him. I don't know if he likes me but I want to kinda show how I feel toward him but not tell him I do like him. Does anyone have any ideas how I can get him to notice me more? Hellppp
