Play Connect 4 with Friends Online — Free Multiplayer

Private rooms, custom time controls, real-time chat, and instant rematches. Send a link, start a game in 10 seconds, no download or signup required.

Private Rooms

Generate a room code, share the link, your friend joins. Works on phones, laptops, tablets.

Real-Time Chat

Talk smack mid-game in the in-board chat panel. Direct messages persist between sessions.

Instant Rematches

Click rematch the moment a game ends. The next game starts in the same room with reversed colors.

Three Ways to Play with Friends

Private rooms. Click Play, choose Challenge a Friend, pick a time control, and send the room link. Your friend opens the link and the game starts immediately. No accounts needed on either side.

Friend challenges. If both of you have accounts and are friends on play4row, you can send a direct challenge from your friends list with one click. Notification fires on their end, they accept, and you are in the game.

Ranked rematches. If you both want the games to count toward your Glicko-2 rating, play a ranked private match. The win or loss updates both ratings, the game appears in your match history, and you can review it move by move afterward.

How to Start a Private Room

Open play4row.com, click Play, then Challenge a Friend. Choose a time control from the list. The system generates a short room code and a shareable URL. Drop the link in iMessage, WhatsApp, Discord, wherever your friend hangs out. They click, they are in, the clock starts when both players are ready.

Want to swap who goes first? Hit rematch — the next game in the same room reverses player colors. Keep playing best-of-five, best-of-seven, or just keep going until someone has to leave.

Time Controls Available

Bullet runs from 0.5+0.5 to 2+1 (the second number is the per-move increment in seconds). For fast pulses without the panic, blitz includes 3+0, 3+2, 5+0, and 5+3. For thinking-friendly games, rapid offers 10+0, 10+5, and 15+10. Each time control has its own rating leaderboard if you play ranked, so you can specialize in the format that fits your style.

Real-Time Chat in Every Game

Every active game has a chat panel next to the board. Messages appear instantly to both players. For longer conversations outside of games, the friends list includes full direct messaging that persists between sessions. Mute or block anyone who gets out of line — both controls are one click from the chat panel.

What play4row Does That Mobile Apps Don't

The standard Connect 4 mobile apps were designed for solo play with ads between every game. Online multiplayer is usually an afterthought stuck behind a paywall or stuffed with banner ads.

play4row is built for online competition first. Glicko-2 ratings track real skill. Instant rematches mean no menu navigation between games. Match history saves every game so you can review later. No ads in-game. No paid tier blocking features. The site is free to play because it is funded by a small studio that cares about the game, not a free-to-play monetization model.

Frequently Asked Questions

Do my friends need to create an account?

No. Anonymous play works for private rooms — your friend can click the room link, pick a username, and start playing in seconds. Accounts are only needed for ranked matches, friend lists, rating tracking, and tournaments.

Can we play on mobile?

Yes. play4row runs in any modern mobile browser on iOS and Android. The board, chat, and all controls are touch-friendly. No app install required.

Is there voice chat?

Not currently. We have real-time text chat in every game and a full DM system between friends. Voice would change the social dynamic of competitive play and is not on the near-term roadmap.

How long does a typical game last?

Anywhere from 90 seconds for bullet to about 15 minutes for the longest rapid time controls. Most blitz games (3+0, 3+2, 5+0, 5+3) finish in 4 to 8 minutes including increment. Casual games can run longer if you take your time.

Can we run a tournament with friends?

Yes. The tournaments page hosts Swiss-format events you can join, and we run scheduled tournaments with prize pools at announced times. For private tournaments among friends, contact us — custom Swiss brackets are easy to set up.
