9 Kings 1.0 Review: How the Full Release Changes the Roguelite Kingdom Builder

I didn’t expect a game about dropping cards onto a tiny 3×3 board to eat so many of my evenings, but 9 Kings did exactly that in Early Access, and the 1.0 release that landed on November 12, 2026 makes it even harder to put down. So, is 9 Kings worth it now? Yes, and at $9.99 during the launch sale it’s an easy call. It isn’t flawless (the RNG can be brutal and huge late-game battles can make older PCs stutter), but very few roguelites pack this much strategy into a 20-minute run.

Our score	8.5/10

Sad Socket, the tiny studio behind it, wanted a casual game for strategy fans who are also very busy people. It worked: 400,000 copies sold in the first month of Early Access, then more than 30 numbered patches. This full release isn’t a reinvention, it’s the finished version of a game that was already great.

What’s new in 9 Kings 1.0 after Early Access

The launch build ships with four game modes, 130+ cards, 140+ decrees, 110+ perks and 80+ quests, plus new sound effects, smoother animations and better performance. Not every Early Access game crosses the finish line in such good shape (my Loftia early access review shows how rough that stage can be).

Joker mode finally lets you build your own deck

Joker mode is the headline feature. Instead of starting with one king’s fixed deck, you pick nine cards from the entire roster and tweak the rules of the run. It turns 9 Kings into a theorycrafting sandbox where you finally test that combo you never managed to draw.

The obvious temptation is to load up on buildings and buffs. Don’t. A deck without enough troops gets flattened the first time a big army walks in, and I learned that one the hard way. Two or three solid units plus your favorite support buildings is a much safer start, and you can always get greedier once you understand how your picks interact.

Daily quests, new decrees and a bigger rainbow card pool

Daily quests give you a reason to boot the game for one quick run. Decrees are where 1.0 quietly adds the most depth: more than 30 new ones bring buffs and rule-bending modifiers that open brand new combo routes. Squeezing value out of them feels a lot like climbing the ladder in my Slay the Spire 2 Ascension guide.

Rainbow cards, the rare and flashy ones, got a big push too. A late Early Access patch had already raised the total to 27, and 1.0 adds more powerful ones on top. When one shows up mid-run it can completely redirect your plan, and that “okay, now I’m building around this” moment is still the best feeling the game has.

How a run of 9 Kings plays in the full release

The core loop hasn’t changed, and that’s a good thing. You make every decision before the fighting starts, then watch it pay off (or blow up) in seconds.

Your kingdom starts on a 3×3 grid and grows every year

You begin with a castle on a 3×3 grid. Each year you draw a hand and place cards on your plots: troops, towers, buildings, enchantments and one-shot spells. Then an enemy army marches in. Combat is automatic, so the real game is adjacency. A Farm adds one unit to a neighboring troop every year, a Blacksmith gives +2% damage to whatever sits next to it, and those tiny numbers snowball into absurd armies.

Three rival nations are rolled at random when a run starts, and you can make peace with one of them. Beat an attacking nation and you loot cards from its pool, so choosing who to fight is really choosing which cards you want. A standard clear ends at year 33 (about 20 minutes on double speed), while the true ending stretches to year 99, closer to an hour.

All nine kings are in, and each one changes how you think

The name finally matches the roster. Beyond the generalist King of Nothing, Greed lives and dies by gold, Stone builds the toughest defenses, Blood floods the board with weak units and self-damage tricks, Nomads has dragons, Spells hits hard with magic, Nature buffs everything around it, Progress is all about upgrading plots, and the King of Time completes the court. Mixing two decks through looting is where the game really opens up.

My advice? Jump to the King of Spells after the starter, since its offense is easy to read. Leave Progress for later; it demands synergy you won’t grasp early, a bit like cracking the best Necrobinder builds in Slay the Spire 2.

Does 9 Kings have multiplayer? Yes, but it’s asynchronous

There’s online multiplayer, but don’t expect co-op or live matches. You face eight rival kings in an asynchronous format to see whose kingdom lasts longest, with the King of Kings title going to the survivor. Other players build far weirder kingdoms than the AI, which is exactly why this mode keeps pulling me back after a few solo runs.

A Casual play option is there too, along with ranking stats and a post-game base review to see why your castle fell. Balance complaints still pop up, so I treat ranked as a fun extra, not an esport.

Is 9 Kings worth it at 1.0?

On Steam, 92% of more than 10,000 English reviews recommend it. Whether it’s for you depends on how you feel about randomness and automatic combat.

Price, platforms and system requirements

On PC it costs $19.99, with a 50% discount for the first two weeks after launch. You’ll find it on Steam, GOG, the Epic Games Store and the Microsoft Store, and it’s included with PC Game Pass. It’s also Steam Deck Verified and runs on Mac, and the minimum specs are tiny: 4 GB of RAM, a GeForce GT 630 class GPU and 500 MB of storage.

The iOS and Android version by Playdigious is free to try with a one-time $8.99 unlock and cross-progression. There are no microtransactions anywhere. One heads-up: when hundreds of units fill the screen late in a run, older PCs can drop frames.

9 Kings vs Slay the Spire 2 and Monster Train 2

Slay the Spire 2 asks you to play every card in every fight, while 9 Kings asks you to plan the board and then watch. If you love turn-by-turn tactical control, Slay the Spire 2 is still the deeper card game, and its newly revealed mode gives it even more legs. 9 Kings scratches a different itch: short sessions, huge numbers and the city-builder joy of watching your kingdom fill up.

Monster Train 2 is the closer cousin, since both are about stacking units and synergies to survive escalating waves. The difference is that Monster Train 2 spreads its fights across floors, while 9 Kings lives entirely on grid adjacency. If you’ve ever argued about the best Pyre Hearts in Monster Train 2, you’ll enjoy agonizing over which plot gets the Blacksmith.

Where 9 Kings still frustrates me

RNG is the big one. Card draws are random, and on higher difficulties I burn more gold on rerolls than I’d like. You also can’t check how strong an incoming army is, so sometimes a run ends and you’re not entirely sure what you did wrong.

The 99-year runs can drag a little, and a few Quest mode challenges feel more like luck than puzzle solving. None of this ruins the game, but it’s why my score isn’t higher.

Personal review

To close out this 9 Kings review, I’m giving 1.0 an 8.5/10. It squeezes Joker mode, daily quests, nine very different kings and run-flipping rainbow cards into 20-minute sessions. It’s perfect for strategy fans with little free time, and if Slay the Spire 2, Monster Train 2 or Balatro gave you that “one more run” itch, you’ll feel at home.

You can play it on PC through Steam, GOG, Epic, the Microsoft Store and PC Game Pass, plus Mac, Steam Deck, iOS and Android. Have you tried Joker mode yet? Tell me in the comments which king you main, what deck you’d recommend, and what you think 1.0 is still missing.
