A studio in Finland with a pixel-art game about playing dice against the guardian of the underworld has just crossed one million downloads. Pepperbox Studios' Dice of Kalma hit the milestone across Steam, iOS and Android this month, roughly ten months after it launched on PC in November 2025.
The number itself is not remarkable in mobile terms - a million downloads is a rounding error next to what a mid-tier gacha does in a weekend. What is remarkable is the shape of it. This is a premium-feeling, deliberately austere roguelike with no live-service scaffolding, and the bulk of its audience found it on a phone.
The Balatro shadow is long, and that is the point
Dice of Kalma is, structurally, a Balatro-like. You build a deck - of skulls rather than jokers - roll five dice, assemble poker hands, and watch the multipliers compound until the score clears a threshold. There are over 70 skulls with abilities that rewrite the rules of a run, eight upgradeable poker hands, and a generous supply of rerolls to push your luck with. Run out of hands and Kalma, the grim guardian, sends you back to the start.
Two years on from Balatro, the obvious worry about this subgenre is saturation: dozens of studios noticed the same thing at the same time, and most of the resulting games are indistinguishable from each other. A million downloads says the ceiling has not been reached yet, at least not on mobile, where the format has structural advantages it does not have on PC.
A run of Dice of Kalma is short, entirely turn-based, and demands nothing of your reflexes. You can play it one-handed, pause mid-hand for ten minutes, and come back without losing anything. That is close to a perfect description of what a phone game has to be, and it is why deckbuilders keep outperforming on mobile relative to how they do on Steam.
A look that costs nothing and reads perfectly on a 6-inch screen
The art direction is doing quiet, unglamorous work here. The whole game is monochrome line art - an ossuary corridor drawn in single-colour wireframe, shelves of skulls receding into black, a reaper looming over the UI - with the palette shifting as you descend. It is the kind of presentation that a two-person team can actually produce, and it happens to be the kind that survives being shrunk to a phone screen with no loss of legibility.
Compare that with any 3D mobile game that has to fight for clarity on a small display, and the advantage is obvious. Every element on screen in Dice of Kalma - dice faces, the bones and multiplier counters, the play and reroll buttons - is high-contrast and unambiguous at a glance.
Still being fed, which is the harder part
The milestone lands alongside a steady update cadence that is arguably more impressive than the download count. Dice of Kalma has shipped several content drops since launch - the Pick Your Poison update earlier this year, and more recently Silent Skulls, which adds costumes, new skulls and harder challenge modifiers for people who have already beaten the base game into submission.
There is a Daily mode, a short fixed challenge that resets every 24 hours, and leaderboards attached to it. That is the cheapest possible retention mechanic and also one of the most honest: no energy timer, no login streak you lose by missing a day, just a new puzzle that everyone plays on the same terms.
The game is also Steam Deck Verified, which is a strange badge for something this at home on a phone, but it fits the pattern. Dice of Kalma works anywhere you can hold a device and think for thirty seconds - and it turns out that is where most of a million people wanted to play it.
