For those who don't know Voltorb Flip: it's a strategy and luck based mini game. On a field with 5 x 5 cards you have to reveal all cards with the numbers 2 or 3 on them to win. You loose, if you accidentaly reveal a Voltorb instead. For each row and column you get the numbers of Voltorbs and the overall sum of all numbers. You can increase your chances of winning with strategy and logic, but on some decisions it's pure luck wether you reveal a Voltorb or not. Each 2 and 3 you reveal will act as a multiplicator for the coins you are winning.
(for example, if you reveal a 2, a 3 and then again a 2, you will get 2 x 3 x 2 = 12 coins)
Spoiler:
PS: I usually make 1000 coins in 15 minutes. If the admins/mods think this is too much we could raise a fee for playing. Maybe it costs 50$ per round you play? (you usually win between 24-48$ in the first level of the game), so you would first have to invest a little bit before you have the chance to win a little bit more money
