Kewlio: I'll see you guys next time

As long as you have enough coins to basically prime it, as well as a way to set the buttons to turbo, it will pretty much print money for you without your needing to do anything else. While the odds of getting a match are pretty low, it will eventually scroll the word "Kick!" or "Punch!" at you, resulting in that hit having much higher odds. Either one will change the reels to numbers 1-10; the middle row's numbers are multiplied, and you get that many coins. Kick is one bonus pull, and Punch is three. This ultimately makes the machine pay out WAY more than you put in. Then, just stock up on crap from the coin counter, and resell to the item shop for G. Basically infinite money.
