Bascially one player acts out the word/phrase while the others guess it.
The player acting out the word should not speak but can interact (without sound) with their team. Teams should take timed turns acting out words. During a turn the acting player should act through as many words as they can. When the word is guesses, they move on to the next word. There is no skipping words. Each correctly guessed word is worth one point. Once the time is up, the other team gets their turn.
