About
The name of the gamble is "janken." Players are split into three teams: A, B, and C. Team assignments are random. [Janken Rules] A card game where the team that acquires the most chips using Rock, Paper, and Scissors cards wins. Each round, a total of 15 cards (Rock, Paper, and Scissors) are distributed randomly among the three teams. Each team is also given one Joker, which can be played as Rock, Paper, or Scissors (usable only once per game). Each team starts with 400 chips (100 per member). Games are played 1-on-1 at the dealer's table. Players submit one card and an ante of 5 chips. The attacker starts the betting; once both call, the cards are revealed. The winner takes all chips in the pot. If a player runs out of chips, they are out and can no longer participate. The count of cards played and the chip totals for each team are public information. There are 5 rounds in total, with 6 plays per round. Opponents can be challenged freely. A round ends immediately if any of the three teams runs out of cards.
