How does codenames work

Overview

Codenames is a popular social word game that blends deduction, teamwork, and creative thinking. It was designed by Czech game designer Vlaada Chvátil and published in 2015 by Czech Games Edition, quickly gaining international acclaim for its simple rules and deep strategic possibilities.

The game is best played with 4 or more players, divided into two teams: red and blue. A 5x5 grid of word cards is laid out, and each word represents a potential clue target. Hidden roles determine which words belong to which team, and one word is designated as the assassin—guessing it results in an immediate loss.

• Grid size: The game uses a 5x5 grid, meaning exactly 25 distinct word cards are placed face up at the start of each round.
• Word distribution: Of the 25 words, 8 belong to the red team, 7 to the blue team, 1 is the assassin, and the remaining 9 are neutral.
• Roles: Two players act as spymasters, each knowing the secret color assignments, while the others are field operatives who guess.
• Clue structure: Spymasters give one-word clues paired with a number indicating how many words on the board relate to that clue.
• Win condition: The first team to correctly identify all their assigned words wins, but selecting the assassin card ends the game instantly.

How It Works

Each round begins with the spymaster examining a key card that reveals the secret color identity of each word on the 5x5 grid. Using this information, they craft clues to guide their team without revealing too much to the opposing team.

• Spymaster: This player knows the secret identities of all 25 words and must give clues to guide their team. They cannot point or use gestures.
• Clue word: The spymaster gives one real word (e.g., 'Ocean') and a number (e.g., '3') indicating how many words on the board relate to that clue.
• Guessing phase: The field team discusses and selects up to the number of words indicated by the clue, tapping each word card to reveal its color.
• Turn end: A turn ends when the team guesses incorrectly, chooses a neutral word, or completes all guesses. Play then passes to the other team.
• Assassin card: If a team guesses the word marked as the assassin, they lose the game immediately, regardless of score.
• Game end: The game ends when one team identifies all their words or if the assassin is selected. Ties are rare but possible in variant rules.
