About this game
Once Upon a Galaxy is a fast-paced, free-to-play card battler of cosmic proportions. Captain a crew of characters from myth and fairytale lore into battle across a spectacular galaxy in search of allies, spells, and treasures to ensure your ultimate victory!
Begin each game by selecting a Captain with its own unique effect.
Will you choose Dorothy to help complete her friends’ quests? Or Dragonmother to discover what hatches from her Mysterious Egg? Play as Indiana Clones to "clone" your best three treasures, or lead a troupe of toys as Geppetto!
More captains are released each month, so there’s always something new to try!
Galaxy features an eclectic cast to help you on your journey. Recruit characters and cast spells each round to prepare for your next challenge. Carefully position your cards while planning your turn—then enjoy their auto-battle against other captains and crews!
Upgrade your crew throughout the game. Character-copies give bonuses and discover powerful treasures. Enhance your board directly to keep buffs as you replace characters. The most powerful cards appear later in the game—find a Legendary crew to help make you the last captain standing!
You can capably lead any odd character, but your most powerful crews will come from smartly-selected synergies. Combine treasure effects with characters’ abilities for powerful outcomes. Leverage powerful character factions, each with their own focus, such as treasure-loving Dragons, spell-enhanced Mages, or Toys which summon additional characters during the fight!
In addition to the common pool of cards you encounter each game, each captain commands its own list of collectible elite characters to customize your plans. Select 12 cards before the game—they’ll be mixed into your card pool to potentially draw!
No timers, no pressure. Galaxy's matchmaking and async-multiplayer mean you can battle fun-but-challenging opponents whenever you want. Face real boards from other human players’ earlier games. Your finished run will join the opponent pool for others to challenge. It's fast, strategic, and endlessly fun!
When you're ready to crank up the intensity, you can play with friends in 6-player live lobbies... warning: live lobbies are the ultimate competitive experience!
While our Steam build is great for the desktop experience, Galaxy is also available on your phone or tablet! With a cross-platform account, you can sync your progress no matter which device you use and so can explore Galaxy on-the-go!
Once Upon a Galaxy is created by Million Dreams Games, an indie studio boasting a talented team. Our leads have worked on iconic games like Magic: The Gathering, Hearthstone, and Runeterra. We’re diehard fans of the card and auto-battler genres.
We believe in building a fully-functional free-to-play experience. We partner with wonderful artists to bring our vision to life (no AI artwork is used in Galaxy).
If you love our game too (we think you will!) and want to support us, you can boost your collection rewards or style your favorite cards with alternate-art skins. A monthly Galaxy Pass offers both!
Give Galaxy a try and experience the thrill of this groundbreaking card battler.

Paint your slots to power up your team, and discover new characters who make an impact as soon as you encounter them.Chormaria’s preorders go live in September, with the full launch arriving soon after. Here is your first look at what’s coming:Your Board is Your CanvasIn Chromaria, a little color goes a long way. The new Paint mechanic brings life to your board, using color to help your team grow.Each color effects the painted slot:Red Paint – Buff character abilities here by +1 Attack each fight.Yellow Paint – Buff character abilities here by +1 Health each fight.Blue Paint – When you cast a spell, give this slot +1/+1.Every brushstroke counts: whenever you paint, that slot gets +1/+1 regardless of which color you use.But the fun doesn't stop there… what happens when you combine primary colors?

Balance Patch - August 2026
The mid-month balance patch is here, let’s dive into the changes!Balance ChangesDungeon Master: now finds a Hero or Villain in each turn’s first shopRunefeather: now offers the Boon as a fourth choice (was replacing one of your treasures)Silversmith: now buffs treasures discovered with its abilityWe Are Blorg: now gives +5 Attack to your Toys with 5 or more character typesDungeon Master, Runefeather, Silversmith, and We Are Blorg are all getting tune-ups, enhancing their previous abilities to help them shine.Morgan Le Fae: now buffs herself (was a random character)Fae Familiar: now also buffs another random characterThis pair of spells-matter uncommons are getting buffed, too. Morgan now exclusively buffs herself (fitting for a selfish Villain) to get more value from Ranged. Fae Familiar doesn’t mind sharing buffs, though - just give a friendly pat first!Crystal: Quest is now Have three Mages (was Have seven total treasures and Mages)Crystal’s original Quest was a little too ‘free’, working with any pile of treasures and often summoned by Destiny for massive value. This change keeps the focus on rewarding Mage strategies, rather than being an auto-include in most decklists.Tsarmina, the Tyrant: supported characters now buff their slot when they Hunt (had buffed themselves)Innkeeper: now improves when any of your characters HuntsThis pair of Hunt-matters Supports are a bit stronger, making them more enticing in deckbuilding for Hunt strategies. (and now synergies well with Black Beard)Sorcerer’s Mop: now buffs summoned Toys (was any summoned character)Sorcerer’s Mop has long been a Legendary powerhouse, filling a role as an end-game strategy available in the shared card pool. However, recent additional summoners have made it too easy to take advantage of. With its new focus on Toys, Mop will still be powerful, but should require a bit more planning to pay off.Bug FixesArtemis now works with Butcher's Cleaver (finds Secret Rares)Introductory Rerolls Discount Ending So...Read full article on Community Announcements (SRFS)AnnouncementsOfficial
