Sidereal Confluence: Bifurcation is an expansion for Sidereal Confluence released in 2022 for 4–9 players, 120–180 minutes per game, and ages 14 and up. It was designed by TauCeti Deichmann and its main mechanics are Variable Player Powers, Trading, and Auction / Bidding.
Sidereal Confluence: Bifurcation includes variations on each of the nine original species, providing entirely new mechanisms, new strategies, and new avenues for negotiation! These variants represent different aspects or factions within their societies — from Deep Unity to the Zeth-Charity Syndicate. The alternate versions may be freely intermixed with the originals, but both versions of a species may not be used in the same game. This expansion features iconography and graphic design that match the Remastered Edition of Sidereal Confluence; however, since so few components in the game are randomized, you should be able to use it with the original edition without too much difficulty.
Sidereal Confluence: Bifurcation supports 4–9 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 Sidereal Confluence: Bifurcation is 120–180 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 Sidereal Confluence: Bifurcation 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.
Sidereal Confluence: Bifurcation has a complexity rating of 4.0 out of 5 from BoardGameGeek players, which makes it a heavy 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.

The catalogue lists Sidereal Confluence: Bifurcation as an expansion for Sidereal Confluence.
