Play LinesClash online with friends

Start an online game in four steps

1. Create your room. Open Play Online, choose Invite friends, then select your mode, board and rules. Classic uses cumulative scoring; Battle is a two-player HP duel.
2. Share the invite. Copy the room link and send it to your friends. Each person opens it in their browser and takes a seat. Guests can join without signing in.
3. Get ready together. Wait for everyone to connect, then each player presses Ready. The host starts the match once every seat is filled and ready.
4. Play on the shared board. Take turns placing symbols. The server confirms each move and sends the updated position to everyone.

Two players, three players or four players?

Choose Duel for two, Triple for three or Chaos for four. Marathon and Insanity support 2–4 players on larger boards. Classic matches keep scoring until the board fills. You are not eliminated when someone makes the first line of three.

For a quicker two-player match, choose a 6×6 Duel where offered. For attacks, guards and abilities, open Battle Mode, select Online friend and create the Battle room directly.

Joining from a chat app or reconnecting

Open an invite in the browser you want to keep using. If you first opened it inside a chat app and then switch browsers, close the earlier tab. In a private lobby, a new arrival can take a disconnected seat; a connected player keeps their place.

A full room needs an available seat. Ask the host to check the connected players or create a new room with the right player count. If a match has already started, new players cannot join mid-game. Reloading in the same browser can restore your own seat while it remains available.

Voice, guests and playing nearby

Private rooms offer optional live voice. Each person decides whether to join room audio and grant microphone access. AI character voices are a separate game setting. You can play without a microphone.

If everyone is in the same place, Same Device lets 2–4 people take turns without creating an online room. For automatic matchmaking instead of a private invite, choose Quick match. See the new-player guide for rules and the privacy page for account and voice details.
