About this app

One Deck Galaxy is the spacefaring successor to the hit roguelike One Deck Dungeon from Asmadi Games and Handelabra Games.

Roll your dice and cleverly use them to build up your civilization from its humble homeworld, growing to create a Federation spanning countless star systems.

Each time, build a new civilization (or two) by combining a Homeworld and Society. Each Homeworld has a unique ability, starting tech, and milestone. Each Society has a unique ability, 3 milestones, and a unique tech that powers up the more milestones you achieve.
- 5 Homeworlds: Elemens, Felisi, Plumplim, Timtillawinks, and Zibzab
- 5 Societies: Botanists, Explorers, Guardians, Mathematicians, and Scientists

You’ll need to:
- Establish colonies to gain more resources and most importantly: more dice!
- Develop techs that grant you powerful new abilities.
- Study locations and launch probes to further your scientific research.
- Build fleets to extend your influence throughout the galaxy.
- Achieve milestones that signify the growth of your civilization.

All of these goals are accomplished by effectively managing and using your dice, focusing your efforts on what you deem most important. All of your dice will be useful in some way, regardless of the roll, so One Deck Galaxy is a game more of strategy than luck!

Standing between you and your cosmic destiny each game is one of several Adversaries:
- Neeble-Woober Colony Fleet - Sentient cephalopods with a simple belief: They're the best!
- The Hungry Nebula - A mysterious space phenomenon that seems to swallow everything in its path.
- The Optimization Calibrator - An Interstellar Social Media Entity that knows you, what you want to do, and what you should do.
- Dark Star Syndicate - Just scientists asking questions! Like: "What if we turned off all the stars?"
- Preservation Authority - Encasing planets in ice for their own protection and safety

You’ll have to split your efforts between growing your own strength and confronting them directly. Every Adversary has its own set of rules and abilities, and you’ll need to come up with different plans and tactics to defeat each one!

You can either play individual game sessions, or play a 6-game progressive Campaign, providing you with opportunities to upgrade your abilities along the way. With hundreds of possible setups, One Deck Galaxy is a different experience every time you play!

One Deck Galaxy is an officially licensed product of “One Deck Galaxy” from Asmadi Games.

★★★★★

Game's great! This adaptation is the definitive way to play One Deck Galaxy, maybe even more so than the physical copy. This digital version retains the tactility of the dice rolls and the assigning of them, but also enforces the many rules and checks the game requires. A nitpick would be that the location/encounter cards could be like 20% bigger as there is just wasted space around. The cards are smaller than they need to be, but very playable. Buy this! It's better than onedeckdungeon!!!

I know it's a steep price to ask for but honestly it's everything that made their previous game great but even better here! I'm not a huge sci fi guy myself and I liked the classes of the other game more so I was hesitant but this game is just an upgrade through and through!

★★☆☆☆

Loved 1DD. Sadly, 1DG is cluttered, needlessly complicated, and poorly documented. What is Swell Effect? What are black stars under tech stars? Location cards are tucked -- why and to what effect? Told I could get Adversary Discs for successful confrontations, but not awarded and no way to grab them. Looks promising, but not there yet. Needs an index for EVERY game term and mechanic. Needs expanded rulebook with robust explanations and examples.

★★★☆☆

Big fan of the OneDeck series, and am looking forward to playing this as well, however the app is not visually optimized for smart phones. Would like to see a setting allowing for font size to be increased. Hard to play a game you can't see. Will edit review when this option is available.
