Each player aims to deliver a love letter to the princess with the assistance of collaborators.
First, one card is dealt to each person, and one is discarded face-down from the round (so the process of elimination cannot be used to prove which cards are left) and the rest are deposited face-down into a deck in the middle. During each player's turn, they draw one card from the deck and play either that card, or the card they already had. After processing the effect described on the discarded card, the next player gets a turn. This is repeated until either the deck disappears, in which case the player holding the highest card wins the round (if tied, then the player with the highest total of cards in their discard pile), or until all players but one are eliminated, in which case the remaining player wins the round. The deck (including the discarded card) is shuffled, and play begins again. Once a player wins the game, that player receives a token of affection. The game ends when one player has obtained a predetermined number of tokens of affection.
