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.

good game with multiplayer bugs

Overall, the game runs really well on single player mode. Multiplayer is not really stable.

First the good. Terraforming Mars is an awesome board game! The digital board is gorgeous and everything is intuitive if you’ve played the board game before. I really like the fact that bookkeeping is completely handled for you. The actions tab lets you see how many possible actions you or your opponent have left. This is all fantastic and an improvement over the physical board game.

With that said, multiplayer is deeply flawed due to bugs. The karma system is meaningless with the current bugs in place. Games will hang or you will get kicked out while a robot takes you actions. I’ve found that when this happens you can’t log back on and take control. If you forfeit you will lose karma, which keeps you from getting desirable matches going forward. Since the games are typically 75 to 90 minutes long even in digital mode, this is a big drawback. I haven’t dropped intentionally for the last few days but keep losing karma to these issues. In addition, I haven’t been able to figure out how you add a friend online. If the multiplayer issues were fixed, this would be 5 star app for sure. With these bugs, I can only give it 3 stars as multiplayer can be very frustrating to play. You can get a real match in here and there but my success rate has only been around 50%.

Luck and Strategy in a Fin Package

This is a fun game. It takes both luck and strategy to win it. If you don’t get the right cards, there’s no way to win. But if you don’t play the cards you have strategically, you won’t win, either, making the game a nice balance of expert play and balance. The mobile version takes away much of the bookkeeping tedium and mental overhead that you get when you play the board game face to face, freeing players to focus on the strategy more than on just what plays are possible. In that way, the mobile version improves on the physical game. Highly recommended for folks looking for a fun game that requires some thinking, but doesn’t bog down in slow play or deep strategic contemplation.

One minor nitpick: The solo version does not credit a game as a win if the last couple greenery tiles come in the build phase after the last turn. There’s no point even having that phase if those extra tiles aren’t the difference between winning and losing. IMO, that situation should credited as a win.

Good implementation needs a few things

First my brother and I have both played their actual board game so it was fairly easy for us to learn the digital version. As much as we loved it we couldn’t help but mention how difficult it’d be to learn the game because there were multiple things we had to search for in the Ui. However we were able to do everything we expected to through the game, it is a great digital version as it’s not lacking in any features we could find. My largest complaint is that it has no notification system so it is really only worthwhile to play if both players are going to play live. The online component gives the option to put time limits on turns but that doesn’t work great because you have to constantly go back into the game to check if it’s your turn. Even that wouldn’t be awful but it takes a good 15-30s to resume your game if you leave the app for ANY reason, even a switch to a respond or view a text message you have to sign back in and wait to reconnect. The game needs to implement notifications or have a way to see from the main menu whose turn it is. The only other flaw of the game is there is no undo, if you play a card or an action there is no way to back out of it even if it is still your turn. If those two issues were resolved it’d be a 5 star game
