Sad Socket built a roguelike kingdom-builder around nine-tile grids and absurd card combos, and four hundred thousand copies sold in a month says the pitch landed.

9 Kings drops you on a nine-tile grid with a deck of buildings and units, and it dares you to break the game before the wave counter breaks you first. Sad Socket, a small studio out of São Paulo and New York, built the kind of roguelike where the run is over in fifteen minutes and you're already queuing the next one, which is how a two-person team ends up with four hundred thousand copies sold inside a month.
Every king plays like a different game wearing the same rules: one wants you stacking economy buildings until your army snowballs on its own, another wants you rushing cheap units before the timer punishes patience. That variety is doing the heavy lifting here, and Steam's user base backs it up at roughly ninety-two percent positive across tens of thousands of reviews, enough volume to make 9 Kings one of 2025's more talked-about strategy releases and a Golden Joystick nominee for Best Early Access Game.
The card-combo chase is the real hook. Stack the right synergies and a run that should've ended at King III turns into a rolling snowball nobody on the board can stop, and finding that combination for the first time is the kind of high most roguelikes spend their whole runtime chasing.
The crashes are the real problem, and they're not rare: some players report a hard crash once or twice an hour once things get busy on-screen, which is a lot to ask anyone to tolerate for a fifteen-minute run. Performance also degrades late in a match, right when the board is most chaotic and least forgiving. On top of that, hidden damage and attack-speed caps quietly wall off the infinite scaling the game otherwise encourages, so King IV and beyond can feel less like a harder fight and more like a wall with a specific, undocumented key.
9 Kings earns its sales numbers on design alone, and an 18-month runway to 1.0 gives Sad Socket real room to fix the stability problems before launch. Buy it for the combos, and don't be shocked when it crashes on you mid-run.
