Descriptions

Three lengths of the same text, in the wording of the App Store listing. Quote them whole or in part; no attribution is needed.

Short about 50 words

Stelline is a calm Star Battle-style logic game for iPhone. Every board is generated on your device and verified to have exactly one solution. Place one queen, or two stars, in every row, column and region, and never let two touch. Hints teach the next logical step. No ads, no account, nothing leaves your phone.

Medium about 100 words

Stelline is a calm Star Battle-style logic game for people who solve by reasoning, not by trial and error. Place one queen in every row, column and coloured region, never letting two touch, or switch to 2-star mode on boards up to 11×11. Every board is generated on your iPhone, verified to have exactly one solution, and graded Easy to Expert by a deduction engine with seventeen human techniques, the same engine that powers the hints. Hints count what is out of place before saying where, then walk you through the next logical step. No ads, no account, no internet needed, and nothing about you is collected.

Long about 300 words

Stelline is a calm Star Battle-style logic game for people who solve by reasoning, not by trial and error. Every board is generated on your iPhone, verified to have exactly one solution, and graded by the same deduction engine that powers its hints. No ads, no account, and nothing leaves your phone.

The rules fit in a sentence: one queen in every row, every column and every coloured region, and no two queens touching, not even at a corner. When that feels easy, 2-star mode asks for two stars in every row, column and region on boards up to 11×11.

Boards are built on the device, so there is no pack to run out of: 1-queen boards from 6×6 to 11×11, 2-star boards from 9×9 to 11×11. A deduction engine with seventeen human techniques solves each board the way a person would and grades it Easy, Medium, Hard or Expert from the reasoning it needed; Expert is labelled honestly for boards that need what-if reasoning.

Hints teach rather than tell: the first tap shows how many queens and dots are misplaced, never where; Show me where then highlights the row, column or region behind the next deduction, names the technique, and applies the step only when you ask. No hints and no conflicts earn the Flawless badge.

Tap to cycle a cell, drag to dot a run, undo, redo, a hideable timer and autosave. Pastel palette, Classic black-and-white look or colour-blind mode; light or dark appearance; a crown or a star as your piece. VoiceOver, Dynamic Type and Reduce Motion are supported throughout.

Since version 1.1, Today's board gives every player the same puzzle for 24 hours, with optional Game Center leaderboards, and any board can be shared as a link. Stelline is written from scratch in Swift by one independent developer: a small app that tries to do one thing carefully and give you a fair puzzle, every time.

What is new in 1.1

Stelline 1.1 (September 2026) brings a new Home screen, board codes you can share, and the daily board.

About the developer

Stelline is made by one independent developer, with no team, no publisher and no investors. The app is written from scratch in Swift for iPhone, including its own puzzle generator, exact solver and the seventeen-technique deduction engine that grades every board and explains every hint. It has no network code, no analytics and no advertising, because a puzzle game does not need any of them. The idea is simple: a fair puzzle, every time, on a screen that leaves you alone to think.

Promo codes for reviewers are available on request, and questions about the generator, the solver or the difficulty grading are welcome.
