How to Play Codenames Online Free (No Sign-Up Needed)

Codenames is one of the most popular party board games in the world — over 16 million copies sold. But you don't need the physical box, or even an account, to enjoy a Codenames-style game with friends online. Here's exactly how it works and how to start playing in under 30 seconds.

The rules in one minute

Two teams — red and blue — see the same 5×5 grid of 25 words. Each team has one spymaster who secretly knows which words belong to their team, and guessers who don't. The spymaster gives a one-word clue plus a number, like OCEAN · 2, meaning "two of our words relate to OCEAN." Guessers tap words one at a time: a correct word lets them keep going, a wrong one ends the turn, and one hidden assassin word loses the game instantly. First team to find all their words wins.

How to play free online

On WordSpies — a free Codenames-style game — the whole setup takes seconds: type your name, tap New game, and share the 4-letter room code (or the invite link) with friends. Everyone joins from their own phone or laptop, picks a team, and one player per team taps "Be spymaster." The host presses start, and you're playing. There's no download, no registration, and no cost.

How many players do you need?

Four is the minimum — a spymaster and a guesser on each team. The sweet spot is 6–10 players: guessers can debate the clues out loud (or in the built-in chat), which is where the game gets funny.

Tips for your first game

Spymasters: start with safe clues that link just two words rather than risky three-word stretches. Guessers: say your reasoning out loud before tapping — half the fun is the debate. And whatever you do, think twice before touching a word nobody's sure about: that's how teams find the assassin.
