Delta is a board game released in 2023 for 2–4 players, 90–120 minutes per game, and ages 12 and up. It was designed by Franz Couderc and its main mechanics are Hand Management, Area Movement, and Contracts.
As you know it’s been over 150 years since the inventor of the Perpetual Steam Engine (or PSE), Louise Delargue, wrote her last diary entry before her disappearance. That someone could create an invention to seemingly power cities and other technologies forever, without publishing any findings, remains the biggest scientific folly in the era of PSE. We took the crystals for granted. The supply seemed endless and their energy seemed unending, but we underestimated the growth of populations and the greed for crystal power. As PSE’s across the world try to keep up with the demand, the crystals are breaking. In Delta, players set out on an adventure through the Delta region of Kamargo, to try and gather more information about the crystals that power up the PSEs. as players observe the mechanimals such as the tortoise, flamingo, horses, and bulls. Send your crew to the different sections of the board to try and maximize your actions, and later on add new crew members to your team and even set out on special missions. Manage your hand well, gather enough knowledge, and emerge as the victor in this exciting steampunk adventure. —description from the publisher
Delta 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 Delta is 90–120 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 Delta for ages 12 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.
Delta has a complexity rating of 3.1 out of 5 from BoardGameGeek players, which makes it a medium-weight 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.
