1. when attempting to catch the ball after throwing it, pull your hand back and put it foward again. this will improve your skill and it will impress.
2. make different, new rules to the game to help improve your game. but you must always remember the actual rules so every now and then switch back to the rules of official dooshball.
3. try walking to increase the speed of your catching ability, trust me it works. just take one step then trow it, two steps then catch it and then raise the amount of steps one by one.
