How Stelline came to Android with its puzzle engine written in Swift: why a Kotlin port was out, what the Swift SDK for Android cost, how parity holds.
Andelis Studio · 3 October 2026 · about 5 minutes Stelline is a Star Battle-style logic puzzle: place one queen (or two stars) in every row, column and coloured region, never two touching. When we started the Android version in September 2026, the question was what to do with that engine. Every day Stelline offers Today's board: the same 9×9 (one queen) and 10×10 (two stars) to everyone.
