About
About MASTEN Play
MASTEN Play is the app studio of MASTEN AB, a small company in Sweden founded by Mattias Stenhamre. Our first game, Blindle, launched in July 2026 and is now played in ten languages. Since then we've built a family of small apps – each one made to do one thing well.
How we work
- Small and focused. Each app does one job. We'd rather make five good small apps than one big one that does everything badly.
- Honest prices. One purchase or gentle ads. No weekly subscriptions, no tricks in the checkout, always a “Restore purchases” button.
- Correct, not just pretty. Puzzles with exactly one solution, tournament schedules with a fairness receipt, word lists built for every language.
- Real people test it. Our apps are tested by real players before launch; Blindle's daily players shape what comes next.
- Modern tools, human standards. We use modern tools, including AI, to build and translate faster. What we promise is the result: apps that work, fair prices and puzzles that are correct.
