There is no need to catch your Boomerang for there is lots of fun to land them as close as possible to your feet.
A good game to play with your friends is drawing a circle on the ground about 2 meters diameter and another around that at about 4 meters. Taking turns, each of you have 3 throws. You get 3 points for landing in the middle circle and 1 point of landing in the bigger one. The first one to score 10 points is the winner.
