First off you need to unlucky the 3rd map (the school) which will cost you 250 tickets. Over on the left side of this map you will see a ball hanging from some string. When you have a dodgeball round (which is completely random) you need to press A into the ball which will make it move around the pole, hopefully hitting a dodgeball. You're best off doing this with a couple mates, as I done it solo and most of the time the AI will kill the balls before you get a chance to even attempt it.
