Classic card games you can play in your browser right now, against AI or against another player. No download, no signup, and a real opponent that actually plays the game properly rather than dealing randomly. The collection covers the games most people grew up with — War, Crazy Eights, Spades, Cribbage — alongside serious international ones like Durak, Truco, Bridge and Indian Rummy.

Seven tools. One opponent. Make every choice count.
For something you can play immediately with no rules to learn, War takes seconds — high card wins, and that is the whole game. Crazy Eights is the next step up and explains itself in a hand. For a proper game with real decisions, Durak and Truco are two of the best card games in the world and are barely known in English-speaking countries. Cribbage and Spades sit in the middle: easy to pick up, genuinely deep once you start counting. Bridge is the deepest game here by a distance and rewards patience.
Each card game has an AI opponent that plays to the actual strategy of the game — holding back trumps, counting what has already been played, and betting when the odds support it. That makes solo play a real way to improve rather than just a way to pass time.
Card games are where house rules diverge most, and scoring is usually where people disagree. Every game has a written guide covering the standard rules, how scoring actually works, the common regional variants, and the strategy that separates a decent player from a good one.
