Same idea: get to 21 and do not go over. But the deck is different, and that changes the whole game. There are only 36 cards, and the picture cards are nearly worthless. A King gives you 4, a Queen 3, a Jack just 2. An Ace counts as 11, but if that would bust you, it quietly turns into a 1. Everything else is worth what is printed on it. Big cards are rare, so busting is harder than you expect, and it all comes down to one question: take another or stop. Two aces in hand is the golden one. It beats everything, even a clean 21. Against the bot It plays like a dealer: draws to 17, and if it is still behind you, keeps pushing and risks going over. A good warm-up before you face real people. Against players Everyone in the lobby shows up in a list. Pick an opponent, set your stake, send the challenge. They accept, you take turns, and the winner takes the whole pot. You can pull a friend in straight through Steam. Coins and decks You start with 1000 coins. Run out and it is no big deal: tap for more or claim the daily bonus, somewhere between 1000 and 5000 at random, once a day. Coins buy card decks: ice, fire, gold, sakura, emerald. Pure cosmetics, they change nothing about the rules. And your deck only shows on your own cards, your opponent sees theirs. There is a global leaderboard as well: the richest players across every server at once. Also inside A tutorial from scratch if you have never played. Full English and Russian, cards included. And calm background music that ducks out of the way whenever a card lands. ## Updates ### 1.0.2 Aug 18, 2026 · Version 1.0.2 now seat 2 to 6 players, you pick the size when you create one **Added** -
