Codenames Online
Give one-word clues to help your team guess secret words on the board. Codenames Online is the beloved party game of spymasters and spies.
About This Game
Codenames is one of the best party games ever designed, and its free online version makes it accessible to anyone with a browser. Two teams compete to identify their agents (words) on a shared board of 25 words. Each team has a Spymaster who can see which words belong to their team and must give one-word clues to guide their teammates — but the clue must relate to multiple words to be effective.
The brilliance of Codenames lies in its asymmetry. Spymasters agonize over finding the perfect single word that connects "BEACH," "CASTLE," and "SAND" without also pointing to the opposing team's words or, worse, the instant-loss Assassin card. Meanwhile, guessers must interpret clues that are often hilariously ambiguous. "Ocean, 3" — does that mean BEACH, WAVE, and SALT... or is FISH also in play?
The free online version at codenames.game supports custom rooms with invite links, making it ideal for remote play over Zoom or Discord. There is also a Codenames Duet mode for cooperative two-player sessions. The rules take about two minutes to learn, games last 15-20 minutes, and the skill ceiling is surprisingly high — experienced Spymasters develop an almost telepathic connection with their teams. It is a must-play for any game night.

How to play Codenames online with friends
Searching codenames online, play codenames online, or codewords online usually means one thing: you want a free browser room your group can join tonight, without buying the box or installing anything. OnlineParty.Games is an independent directory — we do not host or own Codenames, and the Play Now button above sends you to the official free site. This guide covers where to play, how to host a remote round, what player counts work, and which Codenames-style alternatives (including the Codewords game people find on NetGames) are worth a look. More picks live in our online word games hub.
- Where to play Codenames online free
The official free browser version runs at codenames.game — no account, no download, unlimited rooms. It is the official online version run by the game’s publisher, not something we host, and the Play Now button routes there through our tracked link. Everything the physical box has is in it: two teams, private Spymaster view, the Assassin card, and the co-op Codenames Duet mode. The same game is written up from a tabletop angle on our Codenames board game page.
- How to host a remote round
Create a room, copy the link, and paste it into your group chat — everyone who clicks lands in the same board. Split into two teams, each picks a Spymaster, and each Spymaster taps the key toggle so only their own screen shows the colours. There is no built-in voice chat, so keep a Zoom, Google Meet, or Discord call open alongside the tab; that call is where the real game happens. Planning a whole evening? See our virtual game night guide.
- Best player count: 4 minimum, 6-8 sweet spot
You need at least 4 players so each team has a Spymaster and a guesser. Six to eight is the sweet spot — enough voices to argue over a clue, few enough that everyone gets a say. It stretches to about 20 if you are happy with big teams and a couple of quiet players. For exactly 2, switch to Codenames Duet, the cooperative variant on the same site. For a group under 4 that wants a party feel, Skribbl.io works from 2 players up.
- Setup time: under two minutes to the first clue
Room creation is instant, the link spreads as fast as your group chat, and the rules take about ninety seconds to explain: one-word clue plus a number, guess your colour, avoid the Assassin. Budget two minutes of setup and 15-25 minutes per game, which usually means two or three rounds in a normal game-night slot.
- Codewords: the NetGames alternative
NetGames (netgames.io) runs a Codenames-style clue game called Codewords alongside its One Night Ultimate Werewolf room. It is the same two-team, one-word-clue idea, built phone-first and free with no signup, so it is the better pick when your whole group is on mobile and nobody wants to pinch-zoom a desktop board. Stick with the official codenames.game version when people are on laptops, when you want the licensed word packs, or when you need Duet co-op for two players. Both are third-party sites; we only point at them. Codewords fans usually also enjoy hidden-role games — see Spyfall Online.
- Best alternatives when Codenames is not the fit
Too few players, or someone has played it to death? Spyfall Online keeps the deduction and drops the word grid, Skribbl.io swaps clue-giving for drawing, and Wordle is the low-effort daily everyone can compare over a call. Browse all online word games or the wider social deduction games category for more.

How to Play
Create a room and invite players
Go to codenames.game and create a new room. Share the link with friends — they join by clicking it.
Split into two teams
Players divide into two teams. Each team selects a Spymaster who will give the clues.
Spymasters give one-word clues
The Spymaster says a single word and a number (e.g., "Ocean, 3") indicating how many board words relate to that clue.
Teams guess words
The team discusses and taps words on the board. Correct guesses are revealed in the team color. Wrong guesses end the turn or trigger penalties.
Win by finding all your agents
The first team to correctly identify all their words wins. But beware the Assassin word — guessing it means instant loss.
Tips & Strategy
- As Spymaster, avoid clues that also connect to the Assassin word — the risk is never worth it.
- As a guesser, always discuss with your team before tapping. Group consensus catches errors.
- Start with safe two-word clues rather than going for ambitious four-word connections early.
- Pay attention to what words the opposing Spymaster seems to be avoiding — it can reveal information.
- Codenames Duet (co-op mode) is an excellent date-night option for two players.
