Game rules

1. Two to ten teams. Each team needs one spymaster and at least one operative. Players join freely, or only the host moves them.
2. The spymaster writes one noun and a number beside it, for example river 2. Words that share a root with a card are forbidden. The number does not limit guesses.
3. Operatives vote for a card. When the whole team agrees, a three-second bar confirms the guess. Your own card lets you keep guessing. A neutral card or another team's card ends the turn. The black card eliminates your team.
4. The first team to open all of its cards wins. Opening another team's last card wins the match for them.
5. The host sets the grid, cards per team, black cards and the word list. Starting the match does not reshuffle the board.
