3 pt. contest is THREE 3 pointers from  5 different spots on the floor, (each corner  and each  wing, and the top of the key) without a time limit (or with a time limit long enough so the boys don't have to rush each shot but not long enough so they can line each one up). This way balls aren't flying all around the gym.

The top three scorers would then go to the finals , the contest is repeated with the 3 finalists and the score is carried over from the first round - person with most made 3 pointers in both round wins. In case of tie, take one 3 pointer from each spot to determine winner.
