Card Duel 21

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.
