20-Player UNO — Massive Multiplayer Card Games

Play UNO with up to 20 players in a single room. The biggest online UNO experience anywhere.

🎉 Why Play With 20 Players?

Most UNO games cap out at 10 players. We don't. Our engine supports up to 20 players in real-time, making it perfect for parties, classrooms, team events, and large friend groups. The chaos of a 20-player UNO game is an experience you won't forget.

🃏 How It Works

Games with 11 or more players automatically use two full decks (220 cards), ensuring there are always enough cards to go around. The game engine handles shuffling, dealing, and deck replenishment seamlessly.

2–10 players: Standard 110-card deck
11–20 players: Double 220-card deck
7 cards dealt to each player at the start
Auto-play keeps the game moving if someone is AFK
