Who can try to keep a poker face during a thumb war against a Cavalier? The first to have no more cards in his personal deck win the game. All players start with their own same deck of cards. They then draw 3 cards from it which constitutes their starting hand. In turn, each player plays a card from his or her hand by placing it on the mat in the frame corresponding to one of the 5 families of the game (Spades, Clubs, Jokers, Hearts, Diamonds). Each card causes an effect when it played. Spades and Clubs allow you to put cards from your deck on top of an opponent’s deck. Joker allow you to do special effects. Hearts and Diamonds allow you to draw cards while emptying your deck. As the rounds progress, 5 piles of cards are formed on the mat. The top visible cards of these piles form a combination. As soon as someone notices it, an additional effect is applied. The game ends when one player has no cards left. That player wins the game.
