This machine requires you to time the pressing of several buttons in an effort to make the candy overflow into the slot where you can grab it (there are whole arcades full of similar machines, like the stuff-animal claw machines, etc.). After watching for a while, we had a go ourselves. Amazingly, we won a huge pile of (vanilla) KitKats! We happily shared them with some fellow gamblers, stuffed the rest in our pockets, and victoriously headed out into the night.
