About MSO Games

A solo-dev, veteran-owned indie studio building competitive single-player classics.

The short version: One developer (Erik), Linux-first, building MSO FreeCell Arena and MSO Minesweeper Arena for desktop and mobile. No ads, no behavioral tracking, no microtransactions, no dark patterns.

Who's behind this

Hi — I'm Erik, the solo developer behind MSO Games. I started this project because I love playing FreeCell and I wanted this game to exist. I spent a long time trying to get other developers to understand the experience I had in mind — competitive, deep, ad-free, with real visibility into how you actually played — and eventually realized that if it was going to exist at all, I was going to have to build it myself.

Ads in games are something I feel strongly about. They destroy the flow and the enjoyment of a game — the whole point of a coffee-break round is the coffee-break feeling, and you can't have that when a video ad is shouting at you between hands. So there are none in MSO Games today — and if that ever has to change, you'll hear it from me here first, plainly and ahead of time.

My professional background is in Business Intelligence, which is where the analytics depth of MSO Games comes from — per-deal leaderboards, skill radar charts, game playback, percentiles, the works. Showing players how they actually performed, against a comparison set that means something, is the part of this project that genuinely excites me. Most card games have stat screens that exist; very few have stat screens that say anything useful.

Development happens on Linux, with cross-platform builds for Windows, macOS, iOS, and Android. The Linux build isn't an afterthought — it's the build I run every day.

What we ship

Both games run natively on Windows, macOS, and Linux (Electron; code-signed on Windows and macOS). FreeCell is released on Google Play (Android) and the App Store (iPhone and iPad); Minesweeper on mobile is next on the list. See the roadmap for what's shipped and what's coming.

Trust & verification

Windows and macOS builds are code-signed and OS-verified — Azure Trusted Signing on Windows (Authenticode/SmartScreen), Apple Developer ID with notarization on macOS (Gatekeeper) — and your operating system will refuse to run, or warn loudly, if those signatures fail. Linux has no standard equivalent for AppImages, so every release ships a SHA256SUMS file alongside its downloads (FreeCell, Minesweeper): save it next to the file you downloaded and run sha256sum -c SHA256SUMS --ignore-missing. The same file lists the Windows and macOS installers too, if you would rather check for yourself. Mobile builds are distributed through Google Play and Apple's App Store with their own signing requirements.

How we run things

MSO Games runs as close to the inverse of the modern free-to-play playbook as we can:

The game is free to download and play on every platform, and so is the online side — leaderboards, rivalries, group play and hosting, daily challenges, your games recorded and kept to watch back, and Hardcore with them. A Supporter subscription will add depth on top of what everyone gets — more ways to look back on your own play, a supporter look for your table, and the mark beside your name — and we'll describe it precisely when it is for sale; it isn't yet. That will be a low flat subscription, and where a store can't bill monthly, Steam included, the same comes as a single annual price instead. All of this is how it works today. If any of it changes, we'll say so here, plainly and ahead of time.
