Here's how it works: All the cards are shuffled and dealt to the players. Each player holds their deck so that only they can see the top card. One player starts by naming a technical detail of their choice, e.g., engine power. Then, all players take turns stating the corresponding values of their top card. The player with the highest value wins the cards from the other players and places them at the bottom of their stack. As soon as a player runs out of cards, the game ends. The winner is the player who has collected the most cards. Of course, the classic quartet game can also be played with these cards.
