Take every SPADE card out of a deck of cards except the Queen of Spades.
You now have 40 cards: Deal them out among any number of players (more is better).
Play a single card.
2-10: Valued at 2-10.
JQK: Valued at 11, 12, 13.
Ace: Valued at 14.
DIAMONDS: Give someone this card. They have to match its value by giving you cards in return whose value totals its value.
HEARTS: Give someone this card. They have to show you their hand unless they give you a single card back of greater or equal value.
CLUBS: Play this card face-up. The player you attack must discard a card; if it’s the QUEEN OF SPADES, it’s played immediately. You keep this card after playing it.
QUEEN OF SPADES: The game is over. If you have the most cards in hand, you win the game. Otherwise, everyone else wins the game.
Countering with CLUBS.
Whenever anyone plays a HEARTS or DIAMONDS card against you, you may discard a CLUBS card (of any value). You get their card and the card’s effect is cancelled.
Whenever anyone plays a CLUBS card against you, you may discard a CLUBS card of greater value to destroy it. Normally playing a CLUBS card to attack returns the card to its player’s hand.
Whenever anyone discards a CLUBS card to counter one of your cards, you may discard a CLUBS card of greater value to… counter-counter. This chain can go on forever.
Whenever anyone plays the QUEEN OF SPADES, there's nothing you can do.
