Every once in a while you are stuck in level. So what you need is the Item slot machine! When you fail the stage more then 15 times you get to use the Item slot machine! It gives you a stat buster item that boosts towers for the rest of this attempt. The more rare the item is the more rare it will apear. DougieBomber12 (talk) 04:29, May 9, 2015 (UTC)
