Terraforming Mars – The Ultimate Engine Building Strategy Game
Transform the Red Planet into a habitable world — manage resources, play project cards, and build the most powerful engine in modern strategy gaming.
Terraforming Mars is one of the most celebrated strategy games of the last decade. Designed by Jacob Fryxelius and published by Fryxgames, it places players in the roles of competing corporations working together — and against each other — to make Mars habitable for humanity. Raise the temperature, fill the oceans, and cover the planet in oxygen-producing greenery.
With over 200 unique project cards, six playable corporations, and a deeply satisfying engine-building progression system, Terraforming Mars delivers one of the richest strategic experiences in modern board gaming.
Players who invest time in Terraforming Mars consistently describe the same experience — each session reveals new card combinations and strategies they hadn't considered, keeping it fresh for hundreds of hours of play.
What Is Terraforming Mars?
Terraforming Mars is a competitive engine-building strategy game for 1 to 5 players. Each player controls a corporation with unique starting abilities and resources. Over the course of the game, players play project cards — representing technologies, organisms, and infrastructure — that generate resources, place tiles on the Mars board, and advance the three global parameters that determine when the game ends.
The game ends when all three parameters — temperature, oxygen, and ocean coverage — are fully raised. Players score points for their contribution to terraforming Mars, for cities and greeneries they've placed, and for achievements and milestones claimed during the game.
The Three Global Parameters
Temperature
Raise Mars from -30°C to +8°C by playing heat-generating project cards.
Oxygen
Place greenery tiles on the board to raise oxygen from 0% to 14%.
Oceans
Place 9 ocean tiles on the board to create liquid water on the surface.
How Does It Play?
Each round, players take turns playing project cards and taking standard actions — placing tiles, claiming milestones, funding awards — until everyone passes. Then production phases run and players collect their resources for the next round.
The engine-building is the heart of the game. Early rounds feel slow — you're building infrastructure, establishing production chains, and setting up the combinations that will score heavily later. Mid-game the engine starts firing. Late game it can feel unstoppable. The progression from weak corporation to powerful terraforming machine is deeply satisfying.
The 200+ project cards mean every game is different. You never see the same hand twice, and different card combinations open radically different strategic paths. A heat-focused corporation plays nothing like a plant-focused one.

Terraforming Mars vs Ark Nova — Which Should You Buy?
These two games are frequently compared as the leading engine-builders in modern strategy gaming. Both are heavy, rewarding, and deeply replayable — but they feel different at the table.
Terraforming Mars is older, more established, and has a larger card pool. Ark Nova has a more innovative action system and tighter design. Choose Terraforming Mars if you love the sci-fi theme and want maximum card variety. Choose Ark Nova if you want a more modern, refined design. Both belong in a serious strategy collection.

The component quality lets it down slightly, and the learning curve is real — but for strategy gamers ready to invest, Terraforming Mars delivers hundreds of hours of deeply satisfying play. Essential for any serious strategy collection.
