Whenever a "7" card is played players must swap hands with another player, when a "0" card is played all players must swap hands! | The Stacking Rule lets players pass the penalty (Draw +2, +4, +6, +10) to the next player until whoever can't play has to take all the cards combined! | The Mercy Rule says if any player gets 25 or more cards in their hand they are out of the game! |
