Codenames Online: Play Free with Friends + Win Strategies

Discovered Codenames at a friend’s place three years ago. We were supposed to play for 30 minutes. Ended up playing until 2 AM. Then again the next weekend. And basically every game night since.

Thing is, once your friend group gets hooked, you want to play even when you can’t meet in person. Good news: you can play Codenames completely free online. No accounts, no downloads, no weird paywalls.

Here’s everything you need to know – from basic rules for newbies to advanced strategies that’ll make you the Spymaster everyone wants on their team.

What Is Codenames?

Quick background for the uninitiated. Codenames is a word-association party game designed by Vlaada Chvátil, released in 2015 by Czech Games Edition. It won the Spiel des Jahres (basically the Oscar for board games) and has sold over 16 million copies worldwide.

The concept is simple: two teams compete to identify their secret agents using one-word clues. But simple rules don’t mean simple gameplay. The tension when your teammate is hovering over the wrong card? Unmatched.

Basic Setup

Two teams – Red and Blue. Each team picks one Spymaster (gives clues) and Field Operatives (guess words).

25 word cards laid out in a 5x5 grid. Everyone can see the words. The Spymasters share a secret key card showing which words belong to which team:

  • 8-9 words for each team (starting team gets 9)
  • 7 innocent bystanders (neutral)
  • 1 assassin (instant loss if touched)

How a Turn Works

  1. Spymaster gives a one-word clue plus a number
  2. The number indicates how many words relate to that clue
  3. Team discusses and guesses one word at a time
  4. Correct guess? Keep going. Wrong team’s word or bystander? Turn ends.
  5. Hit the assassin? Game over. You lose. Immediately.

Example: Your team needs to find STORM and RAINBOW. You say “Weather: 2” and hope they don’t pick CLOUD (which belongs to the other team).

Codenames Rules for Beginners

Let me break down the actual rules because watching your Spymaster’s face while you hover over the assassin hits different when you fully understand the stakes.

Clue Restrictions

The Spymaster can only say:

  • One word
  • One number

That’s it. No gestures. No tone hints. No “uhhhh” sounds when teammates are wrong. Poker face mandatory.

What you CAN’T use as clues:

  • Any word visible on the table
  • Parts of visible words (can’t say “FIRE” for FIREMAN)
  • Rhymes or spelling hints
  • Foreign translations of words on the table
  • References to card positions (“middle row”)

Guessing Rules

Your team gets to guess up to [number + 1] words. So if the clue is “Ocean: 3” you can guess up to 4 times.

After each guess:

  • Your team’s word: Covered with your color. Keep guessing or stop.
  • Other team’s word: Covered with their color. Turn ends. (Ouch, you just helped them.)
  • Bystander: Covered with beige. Turn ends.
  • Assassin: Game over. You lose.

Winning the Game

First team to identify all their agents wins. Simple. Except it never feels simple when you’re one word away and your Spymaster looks like they’re about to pass out.

Spymaster Strategies That Actually Work

Being Spymaster is harder than it looks. You’re staring at the key, seeing connections everywhere, and watching your team almost pick the assassin. Classic experience.

The Cardinal Rule

Before saying ANY clue out loud, scan the entire board. Check:

  • Does this relate to opponent’s words?
  • Does this relate to the assassin?
  • Is there any possible misinterpretation?

“Animal: 2” seems great for BEAR and WOLF until you notice TIGER is the assassin.

Go for Two-Word Clues First

Connecting two words is the sweet spot. One-word clues are too slow. Three+ word clues often lead to wrong guesses.

Good pattern:

  • Round 1: Give a 2-word clue
  • Round 2: Give another 2-word clue
  • Round 3: Connect remaining words or clean up missed guesses

The Zero Clue Trick

This is advanced but powerful. You can say “Word: 0” to tell your team NOT to pick something.

Example: Your words include BRIDE, RING, FLOWERS, LOVE. But CAKE (which screams “wedding”) is a bystander or assassin.

Say “Baking: 0” first. This tells your team to avoid CAKE. Next turn? “Wedding: 4” and watch them sweep.

Use this when:

  • A dangerous word shares themes with your target words
  • The assassin looks too similar to your words
  • You need to “cancel out” a risk before going big

Category Clues vs. Association Clues

Category clues: “Planets: 2” for MARS and SATURN. Safe, clear, less risky.

Association clues: “Red: 3” for MARS, APPLE, BLOOD. Risky but can connect unrelated words.

Start with categories. Use associations when you need to catch up or make creative connections.

Field Operative Tips

You’re guessing? Here’s how not to be the person who picks the assassin.

Think Like Your Spymaster

Before guessing, ask: “What clue would I give for these words?”

If the Spymaster said “Ocean: 2” and you’re debating between WHALE and WAVE, think about which is more ocean-y. WAVE is more common ocean association. WHALE is an animal that happens to live in water.

Context of your Spymaster matters too. Gaming friend? Tech friend? English major? Their associations differ.

Don’t Look at the Spymaster

Seriously. Don’t make eye contact. Don’t watch their reactions. It’s technically cheating but also just awkward. Make your decisions as a team without trying to read their poker face.

The “One More” Gamble

You got both words from a “2” clue. Should you guess one more to catch up on a previous clue?

Risk assessment:

  • Do you have a strong hunch about an old clue?
  • How many opponent words are left?
  • Where’s the assassin (row-wise, vibe-wise)?

Usually worth the gamble if you’re behind. Not worth it if you’re winning.

Codenames Duet: The Cooperative Mode

Want to play with just one other person? Codenames Duet is built for that.

How Duet Works

Both players are Spymasters AND Operatives. You sit across from each other with the key card between you – each seeing only your side.

Key differences:

  • 15 total agents to find (some overlap on both sides)
  • 9 turns total (not alternating, just 9 clue opportunities)
  • 3 assassins per side instead of 1
  • Both players work together, not against each other

Duet Strategy

Communication is everything. You’re both giving clues, both guessing.

What works:

  • Start with safe 2-word clues to establish communication patterns
  • Use the zero clue to mark assassins early
  • Don’t waste turns on 1-word clues unless necessary
  • Remember: 9 turns for 15 words means you need 1.67 words per clue average

The Sudden Death rule: Run out of timer tokens before finding all agents? You enter sudden death. Now you can only pick green agents – any bystander guess loses the game.

All Codenames Editions

The base game is great, but there are themed versions worth knowing about.

Codenames: Pictures

Instead of words, you get surreal, abstract images. Way harder to give clues because you’re describing visual elements.

“Orange: 2” might connect a sunset picture and a fruit picture. But abstract art means more interpretation variety.

Best for groups who’ve mastered the word version and want a fresh challenge.

Codenames: Disney Family Edition

Disney and Pixar themed. 90+ years of characters, movies, and references. Word cards replaced with Disney terms and images.

Great for:

  • Families with younger kids (ages 8+)
  • Disney superfans
  • Groups with mixed ages

The nostalgia hits hard when you’re connecting “Woody” and “Nemo” with a clue like “Friends.”

Codenames: Harry Potter

Uses the Duet cooperative ruleset, so it’s 2+ players working together. Find all Order of the Phoenix members before Voldemort appears.

Cards feature:

  • Characters (Harry, Hermione, Snape)
  • Locations (Hogwarts, Diagon Alley)
  • Items (Wand, Broomstick)
  • Spells and creatures

If your group knows Harry Potter lore, the connections are super satisfying. “Gryffindor: 3” connecting Harry, Neville, and Sword? Chef’s kiss.

Codenames: Marvel

Traditional team vs team ruleset. S.H.I.E.L.D. versus Hydra.

Features characters and locations from:

  • Avengers
  • Guardians of the Galaxy
  • Spider-Man
  • Doctor Strange

Similar to Disney edition but darker themes. Connecting “Thanos” and “Destruction” is very on-brand.

Other Editions

  • Codenames: Deep Undercover – Adults only. Inappropriate content.
  • Codenames XXL – Same game, bigger cards. Good for large groups.
  • Codenames: The Simpsons – Springfield themed.

Games Like Codenames

Love the formula? Here are similar games worth trying.

Word & Deduction Games

Decrypto – More complex than Codenames. Teams give coded clues across multiple rounds while opponents try to intercept. Strategic depth is insane but learning curve is steeper.

Just One – Cooperative word game for 3-7 players. Everyone writes clues for one person to guess a word. Twist: duplicate clues cancel out. Forces creative thinking.

Werewords – Blends Codenames with social deduction. One player knows the secret word, others ask yes/no questions. But there’s a werewolf trying to derail everything.

Picture-Based Games

Dixit – Surreal art cards. One player describes their card poetically, others pick matching cards. You want SOME people to guess correctly, but not everyone. Beautiful and weird.

Concept – Guess words using only icons. No speaking allowed. Place markers on concepts like “big,” “animal,” “cold” to communicate. Surprisingly challenging.

Social Deduction Games

Spyfall – Everyone gets a location card except the spy. Ask questions to identify the spy without revealing the location to them.

Deception: Murder in Hong Kong – One player knows the murderer. Use abstract clue cards to help investigators find the killer without the murderer catching on.

The Chameleon – Everyone knows the secret word except the Chameleon. Say clues that prove you know the word without helping the Chameleon fake it.

Common Mistakes (And How to Avoid Them)

Spymaster Mistakes

Tunnel vision on your words: You’re so focused on connecting YOUR cards that you forget to check if the clue matches opponent cards or the assassin.

Going too ambitious: “I can connect 4 words with this clue!” Maybe. But can your teammates? Start safe.

Helping the enemy: You said “Boat: 2” for SHIP and SAIL. Your teammate picks ANCHOR. Which is the other team’s word. Classic.

Operative Mistakes

First instinct guessing: Team discussion exists for a reason. Your gut might be wrong. Talk it through.

Looking at Spymaster for reactions: Don’t. It ruins the game.

Forgetting old clues: If the Spymaster said “Cold: 2” three turns ago and you only got one, that other cold word is still out there. Keep track mentally.

Final Thoughts

Codenames is one of those rare games that works for literally any group. Family game night? Works. Party with strangers? Works. Remote team building? Actually works surprisingly well.

The online version removes the only barrier – needing the physical box. Now you just need friends and a voice chat.

Fair warning though: once your group gets competitive, those “casual” game nights turn into strategy sessions. “Remember when you said ‘Animal: 3’ and I picked BUG?” becomes a recurring argument.

Totally worth it.

Now go create a room and prove you’re the superior Spymaster. Or at least don’t pick the assassin on turn one. Baby steps.
