Terra Mystica

The base game has fourteen factions. Each round collects income, then players take one action per turn until everyone passes, followed by Cult bonuses and cleanup. Round six ends directly after everyone passes, without that round’s Cult bonuses.

Transform and Build requires unoccupied terrain directly or indirectly adjacent to your structures. Pay spades according to the terrain cycle; after reaching your home terrain, you may pay to build a dwelling or leave it unbuilt. Unbuilt terrain remains available to others. Use spades immediately rather than saving them; faction exceptions follow the faction board.

Upgrade dwellings to trading houses, then to a stronghold or temple; a temple may become a sanctuary. Return the replaced building to your board, changing income. A directly adjacent opponent reduces the coin cost of a trading house. Temples and sanctuaries grant favor tiles, while strongholds provide faction-specific effects.

Gaining Power first moves tokens from Bowl I to II; only after I is empty does it move tokens from II to III. Spend only from III, returning spent tokens to I. Conversions supplement your action on your turn. Sacrificing Power moves one token from II to III and permanently removes another token from II.

When an opponent builds or upgrades, total the Power values of your own directly adjacent buildings: dwellings one, trading houses/temples two, strongholds/sanctuaries three. Accepting n Power normally costs n−1 points. Reduction is allowed for insufficient charging capacity or avoiding a negative score, not simply to pay fewer points.

Each shared Power action is available to only one player once per round. Priests may permanently occupy a Cult space to advance two or three steps, or return to your supply for one step. Only one player reaches space ten on each Cult, and a corresponding town key is required.

A town forms automatically with at least four directly connected buildings totaling seven Power. Including a sanctuary reduces the building count to three; a specific favor reduces the Power threshold to six. Bridges give direct adjacency; Shipping does not. Mermaids have a one-river-space exception. Choose a town tile and gain its immediate rewards.

Passing ends your actions that round; the first passer starts the next round. In rounds one to five, exchange your bonus card for an available card, without immediately reclaiming the one just returned. Final Cult rankings score 8/4/2 each, but a token still on space zero scores nothing for that track; largest directly or indirectly connected building areas score 18/12/6. Ties pool the occupied ranks and divide, rounding down. Convert remaining resources to coins for one point per three coins, or per two for Alchemists. A final score tie is shared.
