Your goal in Aggretsuko: Work/Rage Balance is to get out of work as quickly as possible — that is, to rid yourself of all cards in your hand. The game lasts five workdays (i.e., five rounds), and whoever has the lowest score once the weekend arrives wins.
The deck consists of 86 cards, with two cards each numbered 1-10 in four suits, along with three 11s, two 12s, and one 13. Each player starts with a hand of thirteen cards. The leader of the round plays a combination of 1-5 cards, then each subsequent player can play the same number of cards but of a higher value or pass. Once all but one person has passed, the cards are cleared from the table, then the last player to play leads something else.
Once per round, when you pass, you can rage, placing your rage card on a card that's currently on the table. When these cards are cleared, you can place the claimed card in your hand.
