Composio is a board game released in 2002 for 2–4 players, 30 minutes per game, and ages 10 and up. It was designed by Jean Fin.
The game includes a board with tracks under each of the 26 letters of the alphabet, and different coloured rocks for each player, to be placed on those tracks. The first player secretely thinks of a word and deposits a rock under one of the letters contained in that word. The next player must think of a word containing that letter and at least another letter; he deposits a rock under a second letter contained in that word, and so on, each player adding a letter to the word. When one player cannot continue, he passes, until a single player remains. The remaining player must announce his word; if it is valid, he scores, if not he deducts points. Cards are also played at the beginning of each round to restrict the allowable words (for example, in a particular round it may be stipulated that words may not include the letter "O").
Composio supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Composio is 30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Composio for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Composio has a complexity rating of 1.5 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
