In the land of Terra Mystica dwell 14 different peoples in seven landscapes, and each group is bound to its own home environment, so to develop and grow, they must terraform neighboring landscapes into their home environments in competition with the other groups.
Terra Mystica is a game with very little luck that rewards strategic planning. Each player governs one of the 14 groups. With subtlety and craft, the player must attempt to rule as great an area as possible and to develop that group's skills. There are also four religious cults in which you can progress. To do all that, each group has special skills and abilities.
There will be two heats that will use the base game rules, plus the Fire & Ice turn order board, if it is available and all players at a table agree to use it. The modified base map from Fire & Ice may also be used if available and all players agree.
As many games as possible will have 4 players, but there may be one or two 3 player games if necessary.
Sixteen players will advance to the semi-final. Advancement will be by most points per the following:
- 1st place: 1000 + (1st place score / 2nd place score)
- 2nd place (4 player game): 100 + 10 * (2nd place score / 1st place score)
- 2nd place (3 player game): 50 + 10 * (2nd place score / 1st place score)
If two players have the same number of points then a random die roll will be used to break the tie.
In the heats both players in a tie for 1st or 2nd will be credited with the tied place. In the semifinal and final ties will be broken by most remaining resources.
The four top seeded players in the semifinal will be seated at different tables. All other seating will be random.
All four semifinal tables will use Fire & Ice bidding to assign factions.
All boards will use the same board setup and factions. Four factions will be chosen randomly from the base 14 factions (excluding Auren, Fakirs and Giants).
A variant that will be used if a majority of semifinalists support it is assigning turn order to the four factions up for bid before bidding starts.
The following expansion elements may be used in semifinal games if available and all players agree to include them: 2015 Essen promo tile set or 4 city tile set and/or shipping bonus tile.
The final will use Fire & Ice turn order and 2015 Essen promo tile set.
If a game does not complete by 5 minutes before end of the scheduled time slot the game will be stopped and final scoring applied to the board state at that time.
