A FRESH TWIST ON AN OLD GAME Card Duel 21 is a free, casual single-player card game that gives the familiar challenge of reaching 21 a fresh and playful twist. Play against the machine whenever you want—no other players, matchmaking or internet connection required. FAMILIAR, BUT DIFFERENT Draw cards and try to get as close to 21 as possible without going over. The familiar foundation makes it easy to start, while special cards and tactical abilities create new choices in every match. PLAY AGAINST THE MACHINE Each opponent plays differently. Some are cautious, while others take bigger risks or respond to how you play. Observe their behaviour, choose your moment and find the best way to win. MORE THAN A GAME OF CHANCE Use limited abilities to reveal information, replace a difficult card or change the direction of a hand. Deciding when to use them adds strategy without making the game complicated. PLAY ALONE, ANYTIME Card Duel 21 is designed for quick, independent play. Start a short match when you have a few minutes or continue your campaign at your own pace. • Free to download and play • Casual single-player card gameplay • A fresh twist on the familiar game of 21 • Play against computer-controlled opponents • Playable offline • No account or matchmaking required • Quick first-to-three matches • Special cards and tactical choices • Increasing levels of difficulty • Personal statistics and winning streaks • Daily rewards and achievements COMPETE WITH YOURSELF Improve your win rate, build longer streaks and challenge yourself against increasingly difficult opponents.
