Terraforming Mars is a board game for 1 to 5 players designed by Jacob Fryxelius and published by FryxGames in 2016, and thereafter by 12 others, including Stronghold Games. In Terraforming Mars, players take the role of corporations working together to terraform the planet Mars by raising the temperature, adding oxygen to the atmosphere, covering the planet's surface with water and creating plant and animal life. Players compete to earn the most victory points, which are measured by their contribution to terraforming and to human infrastructure. These goals are achieved by collecting income and resources which allow them to play various projects, represented by cards that increase their income or resources, build infrastructure, or directly contribute to terraforming the planet. The game was received positively by fans and critics, and received numerous awards. Gameplay Players represent competing corporations who all have a stake in terraforming Mars. The game board depicts the planet's surface, which is represented by an array of 61 contiguous hexes. Each hex represents about 1% of Mars' surface area. Onto these hexes, players can place oceans, greeneries, cities, and other special tiles. The object of the game is for players to complete three terraforming conditions: raise the atmosphere's oxygen level to 14%; raise the temperature from −30 to +8 degrees Celsius; and cover 9% of Mars' surface by ocean (represented in-game as having 9 ocean tiles placed on Mars). Players accomplish these goals by playing cards that represent various technologies or buildings used to terraform Mars. The game is played over a number of generations, each represented as one game round. A generation begins with players drawing cards, then players take turns performing actions (which can be playing cards, using the ability of a card already in play or paying for one of the several actions depicted on the board). Once all players have finished taking actions, players collect income and resources according to their production of the different resources, then the next generation begins. One of the unique aspects in Terraforming Mars is the Terraforming Rating (TR) system. Whenever a player performs an action that advances one of the terraforming conditions, the player's TR increases. A player's TR not only represents the victory points they have earned during the game, but is also added to a player's money income when collecting income and resources at the end of each generation.
