Seka is a card game known by various names such as sikka, sichka, strekoza, trinka, trynka, drynka, tri lista, dva lista, and more. The game can accommodate 2 to 10 players and uses a standard 52-card deck. For games with up to 4 players, a 20-card deck from Tens to Aces is used, while games with 5 to 10 players use a 36-card deck from Sixes to Aces. The game includes a Joker, which can be designated as any card by agreement, typically a Six of any suit.

Players earn points based on card values: Joker and Aces are worth 11 points, Kings to Tens are worth 10 points, and lower cards are valued at their face value. The winner is the player with the highest total points.

The game starts with a dealer determined by a draw. Players ante up an agreed-upon amount, and the dealer deals three cards to each player. Players then decide to discard cards or play. Points are scored for cards of the same suit, with higher cards taking precedence. Players can also engage in bidding rounds and bluffing tactics to win the pot.
