Game rules

The mode is picked in the room before starting. One at a time (the classic): one duel at a time while the rest of the room watches live and bets. Everyone plays: every round everyone fights at once, in pairs that change, with no bets.

In "Everyone plays" there are seven rounds. Whoever is last on the table picks the round's mini-game from three; each duel won scores 2 points and, with an odd number of players, whoever rests gets 1. The last round counts double. The rules below (challenge, bets and final) are those of the one-at-a-time mode.

Each round has a challenger, taking turns around the table. The challenger is offered three random mini-games (ones that have not come up recently): they pick one of them and any other player. The challenged player cannot refuse.

With four players or fewer everyone challenges twice; with five or more, once.

Before the duel starts, everyone else secretly bets on one of the two at the same time, already knowing which mini-game it is. There are twelve seconds; whoever does not bet does not score.

A correct bet scores 1 point. If the players who called it right are fewer than half of those who bet, they went against the majority and score 2.

The two duelists play the mini-game on their phones and the room watches it live. Each mini-game lasts ten to forty seconds and has its own rule, shown before it starts.

The duel winner scores 2 points plus 1 for every spectator who bet against them. The loser loses nothing. If the mini-game ends in a tie, nobody scores.

Once everyone has challenged, the final is played: first place against second place, in a random mini-game. Everything scored in the final counts double, for the duelists and the bettors alike.

Whoever has the most points after the final wins the game. On a tie, whoever won the most duels wins.
