Diktat: Harmonium is an expansion for Diktat released in 2026 for 1–4 players, 60–90 minutes per game, and ages 14 and up. It was designed by Mikael "Pyromago" Cheyrias and Fabien Pellet and its main mechanics are Area Majority / Influence, Secret Unit Deployment, and Cooperative Game.
Harmonium allows to play Diktat solo or cooperatively. Players form a Dissidence group opposed to the totalitarian Administration of the NOC dystopian world, and will be confronted with the machinations of the mighty Ministry of Effort.
Diktat: Harmonium supports 1–4 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 Diktat: Harmonium is 60–90 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 Diktat: Harmonium for ages 14 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.
Diktat: Harmonium belongs to these categories: Horror, Science Fiction, and Expansion for Base-game. Its main mechanics are Area Majority / Influence, Secret Unit Deployment, and Cooperative Game. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The credited designers of Diktat: Harmonium are: Mikael "Pyromago" Cheyrias and Fabien Pellet.

The catalogue lists Diktat: Harmonium as an expansion for Diktat. Expansions add new content, rules or scenarios to the base game and usually cannot be played on their own, so you need Diktat to use it. Check that your edition of Diktat is compatible, as some expansions were revised between editions.
