CREATE LIFE ON MARS Lead a corporation and launch ambitious Mars terraforming projects. Direct massive construction works, manage and use your resources, create cities, forests and oceans, and set rewards and objectives to win the game! In Terraforming Mars, place your cards on the board and use them wisely: - Achieve a high Terraform Rating, by increasing the temperature and oxygen level or creating oceans... Make the planet habitable for future generations! - Get Victory Points by building cities, infrastructure and other ambitious projects. - But watch out! Rival corporations will try to slow you down... That's a nice forest you planted there... It'd be a shame if an asteroid crashed right on it. Will you be able to lead humanity into a new era? The terraforming race begins now! Features: • The official adaptation of Jacob Fryxelius' famous board game. • Mars for all: Play against the computer or challenge up to 5 players in multiplayer mode, online or offline. • Game variant: Try the rules of the Corporate Era for a more complex game.

It also introduces new cards, corporations and a new solo challenge. • Explore a new side of Mars with the Hellas & Elysium maps, each bringing a new set of twists, awards and milestones. From the Southern Wilds to the Other Face of Mars, the taming of the Red Planet continues. • Add the Venus board to your game, with a new Solar phase to hasten your games. Shake up Terraforming Mars with the Morning Star expansion, featuring new cards, corporations, and resources! • Spice up the game with 7 new cards from the Original Promo Pack: Includes everything from the microbe-oriented corporation Splice to the game-changing Self-Replication Robot project. * Try the Big Box Promo Pack and its 23 cards to raise the level even higher.

Verdict
The clearest difference is price: Sjakki at Free against Terraforming Mars's $8.99. Sjakki also leads on in-app purchases (none vs 6) and update cadence (daily vs every 3 weeks). Terraforming Mars's advantage is chart position (#25 vs unranked) and iOS requirement (13.0 vs 18.0). On ads and device support there is nothing between them.
