Postcard Cthulhu is a board game released in 2014 for 1–6 players, 20 minutes per game, and ages 10 and up. It was designed by Joseph Limbaugh and its main mechanics are Cooperative Game and Worker Placement.
Postcard Cthulhu is a cooperative Worker Placement game, where the players are Researchers attempting to postpone Cthulhu from rising from his watery grave. The game is played on a postcard using coins. Each player takes a turn flipping some of the coins in their hand of coins to determine where they are able to play. They then place one coin on the map and this activates the special ability of that particular location. It might allow the players to draw more coins or move coins on the map along arrows, for example. Each turn the current player flips 3 coins for Cthulhu which causes Cthulhu to steal coins from the players or fill up the Carcosa track, limiting the maximum hand size of all players. The players win if they can get 3 heads on two particular locations on the board and Cthulhu wins if it steals enough coins from the players or fills up the Carcosa track. The type of coins used is not important.
Postcard Cthulhu supports 1–6 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 Postcard Cthulhu is 20 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 Postcard Cthulhu 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.
Postcard Cthulhu has a complexity rating of 1.7 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.
