ONE CODE. ONE SHARED TABLE.

No accounts or public matchmaking. You decide exactly who receives the room code.

01

Name yourself

Use a short player name without personal information.

02

Create a room

Share the private five-character code with your friends.

03

Fill the table

Play with 2–10 total seats and add bots where you want them.

04

Start the chaos

The host starts when everyone is ready. Browser and Android play together.

BUILT FOR PRIVATE GROUPS

THE ROOM SURVIVES THE DRAMA.

Real cross-play

Android and browser players use the same server-authoritative rules.

Host controls

Add bots up to ten seats, remove lobby players, and launch a rematch in the same room.

Reconnect recovery

A human player normally has 100 seconds to return to the same seat after a network drop.

Table reactions

Send visible emoji reactions, use game sounds, and join browser voice when your group wants it.

Clear turn feedback

Direction, current colour, playable cards, penalties, and danger states stay visible.

Rules that stay put

The server validates moves, stacking, swaps, passes, UNO calls, and elimination.

BEFORE YOU DEAL

QUICK ANSWERS.

You can draw even with a playable card. Drawing once does not auto-play or end your turn. Two-player Reverse acts like Skip. Finished games can rematch in the same room.
