The group has a multiple-choice question and only two minutes to work it out. The snakes amongst you already know the right answer — and they'll stop at nothing to keep you away from it.
In Snakesss, you deal out the cards and try to answer a multiple-choice question with the rest of the players. The more people who get it right, the more points you cash in — unless, of course, you get one of the snake cards. All the snakes already know the answer, so their job is a bit simpler. To score points, they have to sabotage the discussion and mislead the other players.
