Each player is armed with their own SWEAR WORD card and a stack of FOUL MOUTH cards. As you take turns flipping cards from your stack onto the table, the tension builds. The moment a match is revealed, the two matching players have an all-out battle to see who can say the other player's SWEAR WORD first.
The loser of each face-off has to pick up the FOUL MOUTH stack in front of the face-off winner and their stack of cards. The game continues at a lightning-fast pace until one lucky player plays their last FOUL MOUTH card, securing their victory.
