I was never a fan of the slots. Too luck-based, too little payoff on the rare instances that you actually succeeded, coins were kinda pricy. Voltorb Flip, on the other hand, was a fairly easy, much more skill-based game. I've amassed more coins in Voltorb Flip than I have in every normal game corner combined. It's really not even close. When the Slots stop being a total ripoff, then maybe I'll reconsider.
