In Pis Yedili, also known as Dirty Seven, players are dealt seven cards each and the remaining cards are placed face down in the center of the table. The game starts with the player to the left of the dealer discarding a club. If the player doesn't have a club, they must draw cards from the stockpile until they get a club.

The gameplay is straightforward - each player takes turns either playing a legal card on top of the discard pile or drawing a card from the stockpile. A card can be played if it matches the rank or suit of the previous card, except for Jacks, which can be played on any card and the player must nominate a suit.

Pis Yedili - Dirty Seven offers a variety of special cards with unique effects, such as Jacks that change the suit, 8s that skip the next player's turn, 10s that reverse the direction of play, and 7s that force the next player to draw cards.

The game continues until one player successfully discards all their cards, and the other players score penalty points based on the cards remaining in their hands. The player with the lowest point score after four consecutive games wins.

Overall, Pis Yedili - Dirty Seven is a fun and challenging card game that offers hours of entertainment for players of all ages. Whether you're a beginner or an experienced card player, this game is sure to keep you engaged and entertained.
