I don't know if you've ever tried teaching people how to play Poker or Blackjack in game, but it's an infuriating process. It's also a pain to want to be able to play a character who's good at cheating, but you struggle to cheat in real life. After all, Poker is a game designed to be hard to cheat at, but ideally a game in a LARP would be about setting scenes and creating dramatic moments, as opposed to being a foolproof way to handle money. Thus, this is Devilking!
Devilking is a game with a Dealer and some number of Players. It's about trying to have the highest number card, while also avoiding getting got by an Ace.
The Dealer is actively favoring some players over other players. In order to win, the players are expected to cheat through their noses in order to get what they want. At the end of the day, winning is less important than getting to feel like a cool card player.
I've been playing it sometimes on my own, and it's a lot of fun! I really recommend checking it out if you've got some time to kill.
