You are a Christmas elf tasked with delivering 24 Christmas presents with the help of your co-elves, represented on the cards. To accomplish this, you reveal cards from the deck, one after the other. After every revealed card you have the choice to end your turn voluntarily and deliver all the presents granted by the already revealed cards, or to continue and reveal the next card.
But be careful: As the Advent season is a stressful time for Christmas elves, they are prone to spontaneously falling asleep. One sleeping elf is no problem – the rest continues working as usual, but as tiredness is contagious, the others start yawning as well. And whenever another sleeping elf is revealed, all of them instantly fall asleep: You have busted your turn and deliver no presents at all.
After one of the players has delivered 24 presents or more, finish the current round – the elf with the highest total of delivered presents wins the game.
