Terraforming Mars: Colonies

No. Each Colony Tile allows only 3 colonies total, and each player may have only 1 colony on a given tile unless a card says otherwise. (Rulebook, p. 2)

Building a colony is an action and a standard project costing 17 M€. Place your marker on the lowest available space and take the placement bonus shown inside the track. (Rulebook, p. 2)

Trading is an action costing 9 M€, 3 energy, or 3 titanium—you choose one payment method. Move your Trade Fleet to an available Colony Tile, then take that tile’s trade income and give its colony owners their colony bonus. (Rulebook, p. 2)

No. A Colony Tile can hold only 1 Trade Fleet at a time, and a fleet cannot be moved to the colony track. After the generation ends, all Trade Fleets return to the Trade Fleets Tile. (Rulebook, p. 2–3)

At the end of each generation, during Solar Phase Step 3, return all Trade Fleets to the Trade Fleets Tile and move the white marker 1 step up the Colony track on every Colony Tile. Immediately after a trade, however, move that tile’s white marker as far left as possible, stopping next to player colonies or at the bottom of the track. (Rulebook, p. 3)

The Solar Phase occurs after the production phase. First check whether temperature, oxygen, and oceans are all maxed; if so, the game ends and no further Solar Phase steps are performed. (Rulebook, p. 3)
