Gameplay #

Teams take turns to do the following: #

  1. The team’s Spymaster gives clues
  2. Team’s field operatives guess the codenames to uncover

Spymaster Gives a Clue #

Team’s Spymaster gives a clue about the identities of the agents associated with the codenames (words) on the table

  • Spymaster selects the codenames he/she would like the field operatives to uncover
  • Spymaster gives a one-word clue and shouts out the number of codenames it relates to. This number will indicate the number of correct guesses the team can make for the turn. If the team makes a correct guess form previous clue, they are allowed 1 extra guess
Codenames 1

Field operatives guess the codenames to uncover #

  • Teammates discuss the clue and make a guess by touching one of the codenames on the table
  • If it uncovers an agent belonging to the team, they continue guessing until they uncover all codenames related to the clue
  • The turn is passed to the next team, if any of the guesses are wrong

Team loses if they uncover an Assassin card.

Rules and things to note about Clues #

Clues can sometimes affect the way the game is played.

Here are some information about how you use Clues in the game. They cover the following:

Rules for clues #

  • The clue must be about the meaning of the words
  • Letters and numbers are valid clues as long as they refer to the meaning
  • Must be played in English
  • Can’t say any form of the visible word on the table
  • Can’t say part of a compound word

Homonyms and Spelling #

  • Same sounding words with different meanings/spelling are considered different words
    • You can only use the meaning for that word for your clue (e.g. clue for knight cannot be used for word night)
  • Words spelt the same are considered the same even if they have different meanings/pronunciations
    • You can use the different meanings as clues for the same word
  • You can use the different meanings as clues for the same word

Optional Flexible Rules #

  • Decide if you allow compound words (e.g. mother-in-law)
  • Allow proper names as one word (e.g. George Washington)
  • Allow Common Abbreviation (e.g. CIA, PhD)
  • Allow different meanings for Homonyms (same sounding words) e.g clues for knight for the word night
  • Allow a rhyming clue even if it is not related to the meaning of the word

Expert Rules: Clue number 0 #

  • Spymaster is allowed to call 0 to indicate none of the words are related to the clue
  • The team continues to make at least one guess
  • Limit of guesses no longer applies

Expert Rules: Unlimited #

  • If you have multiple unguessed words from previous clues
  • Spymaster may call unlimited instead of number
  • Limit of guesses no longer applies

Invalid Clues, Keeping a straight face and Sand Timer #

Penalty for invalid clues #

  • Team’s turn ends immediately if Spymaster gives invalid clues
  • Spymaster of other team covers also one of their codenames (words) with their agent card before giving next clue
  • If no one notices an invalid clue, clue is considered valid

Spymasters must keep a straight face #

  • Spymaster must keep a straight face
  • Do not reach for any card while teammates are considering the words
  • When teammate touches a word, consult key card and cover word with card of corresponding colour
  • If teammate chooses correct word, Spymaster must act as though it is exactly the word he/she meant even if it wasn’t

Field operatives (non Spymaster teammates) must focs on the table when making guesses.

They must not make eye contact with the Spymaster.

Timer #

  • If a player is thinking too long, any player can flip the sand timer and ask the slow player to make a decision before time runs out

How do you win? #

Game ends when one team has all their codenames/words covered with their agents. That team wins.

If other team chooses your last word, your team also wins.

If other team chooses a word related to an Assasin, that team loses and your team wins.
