Moja 4ka, also known as "My Four," is a popular Central European card game, particularly in countries like Slovakia and the Czech Republic. It's a trick-taking game with elements of bidding and bluffing, typically played with a standard 32-card deck (A, 7, K, Q, J, 10, 9, 8 in each suit). The game revolves around players attempting to win specific card combinations or "melds" during the play of tricks.

The objective is to score points by winning tricks containing valuable cards and by declaring successful melds. Before the game begins, players are dealt a hand of cards. A bidding phase follows, where players estimate the number of tricks they believe they can win. The highest bidder declares a target number of tricks and chooses a trump suit.

Gameplay involves players taking turns leading cards, and others must follow suit if possible. If unable to follow suit, players can play any card, including a trump card. The highest card of the led suit wins the trick, unless a trump card is played, in which case the highest trump card wins.

Scoring is based on the number of tricks won compared to the bid, as well as the successful declaration of melds. Failing to achieve the bid results in negative points. Melds are specific combinations of cards, like a "Four of a Kind" (the "4ka" in the game's name), a sequence of cards in the same suit, or specific combinations of high-ranking cards. Bluffing is a key element, as players might bid aggressively to intimidate opponents or attempt to mislead them about the strength of their hand. Strategic card play and careful bidding are crucial for success in Moja 4ka.
