Fact sheet

Name	Stelline (listed on the App Store as “Stelline: Star Logic Puzzles”). The name is Italian for “little stars”.
What it is	A Star Battle-style logic puzzle game: one queen, or two stars, in every row, column and region, and no two pieces touching. Unlimited boards, each generated on the phone and verified to have exactly one solution.
Platform	iPhone and iPad (iOS and iPadOS 26 or later; the iPad version also runs on Apple-silicon Macs as an iPad app) and Android phones and tablets (Android 9 or later, 64-bit). Portrait on phones, portrait or landscape on tablets, where the board grows and a 12×12 one-queen size opens. Not available for Apple Watch. Both versions run the same puzzle engine, so Today's board is the same board on both on any given day; leaderboards are on iPhone and iPad only for now.
Price	iPhone: free to download since version 1.5. Today's boards, Daily Rush, Learn, a Starter set of boards and two new boards a day are free; Stelline Unlimited (USD 1.99, one-time, Family Sharing) opens the generator without limit, and stats and history. Android: USD 1.99 one-time purchase with everything in it. No ads, no subscription on either (local equivalents elsewhere).
Release	iPhone: version 1.0 on 9 September 2026; 1.1 (Today's board, Game Center leaderboards, board share links) and 1.2 (Compete) in September 2026; 1.3 (six more languages) on 18 September 2026; 1.4 (Tactics, Learn, four drawn pieces) on 29 September 2026; 1.5 (free to download, Stelline Unlimited, Daily Rush) on 12 October 2026. Android: version 1.0 on Google Play since 2 October 2026; 1.6 (tablets and Chromebooks, what-if marks, the lessons, Tactics, Daily Rush, optional leaderboards, Stats) on 15 October 2026.
Languages	English, French, German, Spanish, Italian, Japanese and Brazilian Portuguese (the app follows the phone's language; this site and support are in English).
Category	Games › Puzzle (secondary: Board).
Developer	Andelis Studio, an independent one-person studio in Coral Gables, Florida; the app is written from scratch in Swift, including its own generator, solver and deduction engine, which run on both platforms; the Android interface is native Kotlin and Jetpack Compose.
Data collected	None. No network code, no account, no analytics, no third-party code. Game Center leaderboards (iPhone only) are optional and off by default; the Android app requests no permissions at all. See the privacy policy.

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 and Android. 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 phone, iPhone or Android, 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 iPhone and Android, for people who solve by reasoning, not by trial and error. Every board is generated on your phone, 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 on iPhone, and any board can be shared as a link. Stelline is written from scratch in Swift by Andelis Studio, an independent one-person studio: a small app that tries to do one thing carefully and give you a fair puzzle, every time.

What is new in 1.6

Stelline 1.6 for iPhone and iPad (16 October 2026) brings the game to iPad, adds what-if marks and gives Learn one lesson per idea of the solver. Stelline for Android 1.6 is on Google Play since 15 October 2026 with the same version, tablets and Chromebooks included, and everything built since Android 1.0: Tactics, Daily Rush, optional leaderboards and Stats.

iPad: the board beside its controls in landscape, two columns on Home, keyboard and trackpad or mouse on the board, Apple Pencil hover, 1-queen boards up to 12×12. The iPad app also runs on Apple-silicon Macs.
What-if marks: a What if? button, switched on in Settings, opens a branch; marks made in it are drawn hollow, Keep makes them firm, Drop removes them all in one step. Off by default.
Learn: Techniques, one lesson per idea from last cells to X-wings, each explained on a real position and tried on a second one, then practice on fresh positions keyed on that idea; Advanced: squeezes, set differences, fish and the what-if step.
Compete: the last week of earlier boards inline, the rest under Earlier days. Hints for fish, finned counts and squeezes say where to look instead of defining the idea.

What is new in 1.4

Stelline 1.4 for iPhone (29 September 2026) adds Tactics, a three-minute rush of positions to read, and Learn, lessons played on a real board. Stelline for Android, version 1.0, is on Google Play since 2 October 2026 with the same game and the same lessons; Tactics follows on Android in version 1.5.

Tactics: every position is a board part-way through a solve; tap the cell where a queen can be proven right now. A right tap scores and moves on, a wrong one costs a life and shows the answer with the idea behind it, named and explained. Three minutes, three lives, a personal record kept on the phone. Positions are cut by the same seventeen-technique deduction engine that powers the hints, from freshly generated boards, so no two runs are alike.
Learn: First steps teaches the rules and the controls on a real board, with the player making every move, and opens by itself on a fresh install; a second lesson introduces 2-star mode. The six-slide rules summary stays under Learn.
Four drawn pieces: a donut, a cat, an elf and a teddy bear, the studio's own artwork, next to the crown and the star.
Home, tidied: Today's board on one line, Continue inside the play card, and Learn, Tactics and Compete side by side.

What was new in 1.1

Stelline 1.1 (September 2026) brings a new Home screen, board codes you can share, and the daily board. Stelline for Android, version 1.0, is on Google Play since 2 October 2026 with the same game, without leaderboards for now.

Today's board: the same board for everyone for 24 hours, keyed to UTC, generated on each phone from the date, so no connection is needed. A 9×9 board in 1 queen mode and a 10×10 board in 2 stars mode, kept separately from the ordinary game so you can leave and come back.
Optional Game Center leaderboards (iPhone): turn Game Center on in Settings to post your time on the daily leaderboards, one per mode; assists and hints are off in Compete, so every posted time is made on equal terms. Off by default; the app still works entirely offline without it.
Board share links: every board has an id now. Share it from the game or from the Solved sheet as a link of the form https://stelline.page/b/<code>; a friend opens it with one tap when the app is installed, on iPhone or on Android, or sees the board and a link to the App Store in the browser. The code can also be typed under Compete.
A redesigned Home: the app icon, a bolder title, your colour palette, and a Continue card that shows the board you left. The board sits centred on the screen with the controls at the edges.
Clear and New puzzle ask before wiping a game in progress.

About the studio

Stelline is made by Andelis Studio, an independent one-person studio, with no publisher and no investors. The app is written from scratch in Swift, including its own puzzle generator, exact solver and the seventeen-technique deduction engine that grades every board and explains every hint; that engine runs on both platforms, with a native Kotlin and Jetpack Compose interface on Android. 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.
