Codenames teaches in minutes, which makes it easy to under-prepare. First games tend to go wrong in the same few ways: a spymaster frozen for five minutes, one loud operative making every guess, and an argument over whether a clue was allowed. A little planning prevents all three.
Keep the Codenames teach sheet on the table. If you need the rules first, start with how to play Codenames.
Before anyone sits down
Set up first: 25 words in a 5 by 5 grid, a random key card in the stand, each team’s 8 agent tiles out, and the bystanders and the assassin in between. Keep the double agent aside until the teach is done.
Split the teams, about equal, at least two players each. Mix people up: couples on opposite sides, regulars spread across both. Seat both spymasters on one side of the table, across from their own operatives.
Big group? Past four or five operatives a side, quiet players tend to stop talking. With a second copy, two games side by side keep everyone in it. Our party games for large groups has more ideas.
Choose the first spymasters with care
The spymaster has the hardest job at the table. The rulebook warns that the first clue can take a couple of minutes before things start to flow. Pick spymasters who are comfortable with a long pause and know the people they are giving clues to. Do not hand the key to the newest player unless they ask for it.
If only you have played before, take one spymaster seat yourself. Your clues teach by example. Your team will have an edge, so hand the key to someone else for game two.
The five-minute teach
Say it in this order, and stop at five minutes.
1. The goal. “Two teams. Our spymasters know which words are ours. They give clues, and we find our words before the other team finds theirs.”
2. The clue. “A clue is one word and one number. ‘Ocean: 2’ means two of our words go with ocean. The spymaster can’t say anything else or react to our guesses.”
3. Guessing. “We talk, then touch one card, and the spymaster covers it. Our color, we keep going, up to the number plus one. A bystander or their color ends our turn. We always guess at least once.”
4. The assassin. Hold up the assassin tile. “One word on the table is this. Touch it and we lose.”
5. Clue rules, short version. “Clues are about meaning. No words on the table, and no parts of them. If a spymaster isn’t sure, they check quietly with the other spymaster.”
Then the spymasters check the triangles on the key’s edges to see who starts. Give that team the double agent, flipped to its color, and play. Zero and unlimited clues can wait for another night.
Agree on clue rules before the first clue
The rulebook leaves a few choices to each group. Settle them out loud now, not in the middle of a tense turn:
- Names. One-word names are always valid. Will you allow full names and titles too?
- Abbreviations. Does “NASA” count as one word?
- Two-word clues. Without an agreement, a clue like “ice cream” needs the other spymaster’s okay each time.
- Soundalikes. Will a clue that only sounds like a word count?
- A timer. The rulebook points to a free phone app, Codenames Companion, with timers for groups that want a quicker pace. Skip it for a first game.
Anything you did not cover, take the rulebook’s advice: do not be too strict.
Keep it moving
- Let everyone play. Operatives discuss a bit, then guess, without letting debate stall the game. Give each person a say before a card is touched. Taking turns touching the card helps quieter players join in.
- Watch the cards, not the spymaster. Operatives should not look for reactions, and spymasters keep a straight face, even as their team reaches for the wrong word. A lucky guess? Act like that was the plan.
- No reminders. A spymaster may not point out a missed word or mention old clues, unless someone asks to hear one again.
Coach the rules, not the guesses
As host, help with the rules: the plus one rule, what makes a clue valid, when a turn ends. “You can still make one more guess” is coaching. “I think it’s PIANO” is playing for them.
When an invalid clue slips out, the turn ends and the other spymaster may cover one of their own words, or the other team can wave it through. Let the other team choose.
After the game
Flip the 25 cards over for a fresh grid, draw a new key, and swap spymasters. A game takes about 15 minutes, so a best of three fits most evenings and gives more people a turn with the key.
Before the rematch, ask the operatives one question: “What did you think that clue meant?” It is the fastest way for a spymaster to improve. Our Codenames clue tips go deeper for both roles, and Codenames for team building shows how much one game reveals about the way a group talks.
