This is a pun out of the ordinary. Your partner is just as much your opponent. In order to explain a little further. The game runs in 4 easy phases.
1: You draw a card.
2: You turn a dice get to see the words on the cards to describe.
3: You randomly draw a partner for this round.
4: You and your partner describe the word on the card.
This sounds very simple. Adding to that the points are given based on how quickly you can get the other players to guess the word, and that you and your partner have to explain the word by saying every other word in the sentence.
