## What is Stelline?

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 ever leaves your phone.

THE RULES
Place one queen in every row, every column and every coloured region, and never let two queens touch, not even at a corner. When that feels easy, switch to 2-star mode: two stars in every row, column and region on boards up to 11×11, still never touching.

UNLIMITED BOARDS, EACH ONE PROVEN
- Built on your device: no pack to run out of, nothing to download.
- Every board is checked by an exact solver before you see it: exactly one solution, always.
- 1-queen boards from 6×6 to 11×11; 2-star boards from 9×9 to 11×11.
- Compete: Today's board for everyone, daily leaderboards, a numbered archive of past boards.

TACTICS: THREE MINUTES, ONE TAP PER BOARD
- 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 fresh run every time, and your own record to beat.

DIFFICULTY GRADED BY DEDUCTION
- A deduction engine with seventeen techniques solves each board the way a person would, from finished rows and neighbour dots to line locks, exclusion, counting arguments, X-wings, squeezes and fish.
- Easy, Medium and Hard boards need direct deductions only, in both modes.
- Expert is labelled honestly: it needs what-if reasoning; a few 2-star boards go beyond what the hints can explain.

HINTS THAT TEACH
- Hint first shows two counters, misplaced queens and misplaced dots, without saying where they are. Zero and zero means your reasoning holds so far.
- Show me where walks you through one logical step at a time: the row, column or region behind the next deduction, then the cells, then the technique with a one-line explanation, applied only when you tap Do it.
- Hints are unlimited, with no cooldown. Solve with no hints and no conflicts to earn the Flawless badge.

LEARN BY PLAYING
- First steps teaches the rules and the controls on a real board, with you making every move. A second lesson introduces 2-star mode.

CONTROLS BUILT FOR CLEAN SOLVING
- Tap a cell to cycle it: empty, dot, queen or star.
- Drag across cells to dot them; start on a dot you placed to erase instead.
- A placed queen or star dots its eight neighbours; completed rows, columns and regions can dot themselves too. Both optional.
- Auto-check stripes queens or stars that touch or exceed a row, column or region. Turn it off for a purist solve.
- Undo, redo and clear. Your game saves itself after every move: leave, come back, tap Continue.
- A timer you can hide. No streaks, no pressure: only Tactics has a clock that counts.

MADE FOR EVERY PLAYER
- An original pastel palette, or the Classic black-and-white look with heavy region borders for players who learned on paper.
- Colour-blind mode: high-contrast colours, a distinct fill pattern for every region and thicker borders.
- Light, dark or system appearance. Your piece: a crown, a star, a donut, a cat, an elf or a teddy bear; your mark: a dot or an X.
- Full VoiceOver support, with hints read aloud; Dynamic Type and Reduce Motion respected throughout. Haptics you can switch off.

PRIVATE BY DESIGN
Stelline has no account, no ads and no analytics. Your boards, settings and progress stay on your phone; nothing is collected. The only online feature is the optional Game Center leaderboard, run by Apple and off by default.

FROM ONE DEVELOPER
Stelline (little stars) is written from scratch in Swift for iPhone, including its own generator, solver and deduction engine: a small app that tries to do one thing carefully, give you a fair puzzle, every time.

## Version history (last 5 releases)

### 1.4.0 — 2026-09-29

Stelline 1.4 adds Tactics, a three-minute rush of positions to read, and Learn, lessons you play.

- Tactics: every board is 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. Three minutes, three lives, your own record to beat.
- Learn: First steps teaches the rules and the controls on a real board, with you making every move, and opens by itself on a fresh install; a second lesson introduces 2-star mode. Both sit on Home under Learn.
- Four new pieces drawn for Stelline: a donut, a cat, an elf and a teddy bear, 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.

### 1.3.0 — 2026-09-18

Stelline 1.3 speaks six more languages.

- Stelline is now available in French, German, Spanish, Italian, Japanese and Brazilian Portuguese: the whole app, including How to play, every hint and its explanation, Settings and VoiceOver. It follows your iPhone's language; English stays the default.
- Compete: Enter a code now sits above the archive, so it stays within reach as the archive grows day by day.
- Controls that adapt to longer words: the Undo, Redo and Clear row, the pickers on Home and the difficulty badge switch to a compact layout when a label does not fit.
- Fairer 2-star difficulty: it now means what it means in 1-queen mode. Medium and Hard are pure deduction (Hard adds the advanced counting techniques), Expert needs what-if reasoning, and Expert is offered at 9×9 too. Boards prepared in advance are regenerated; Today's 2-star board stays Medium.

### 1.2.0 — 2026-09-14

Stelline 1.2 turns the daily board into Compete: one place for everything you play on equal terms with others.

- Compete, on Home: Today's board in both modes, a numbered archive of every past board (#1 is 12 September 2026, one number per day in each mode), and Enter a code.
- No assists, no hints on Compete boards: Auto-check, auto-dots and the hint button are off for everyone there, whatever your settings, so every posted time is made on equal terms. Your settings still apply to ordinary boards.
- One leaderboard per mode. Only today's board is posted; past boards can be played any day and keep your best time and Flawless mark on your iPhone.
- Two-star daily boards are capped at Medium: pure deduction, no what-if step.
- Share text carries the board number ("Stelline daily #14").
- The difficulty badge shows the mode at a glance: a crown or star for 1 queen, two stars for 2 stars.
- The 7×7 practice board moved to How to play.

### 1.1.0 — 2026-09-12

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

- A redesigned Home: the app icon, a bolder title, your colour palette, and a Continue card that shows the board you left.
- Every board has an id now. Share it from the game or from the Solved sheet; a friend opens it with one tap on the link, or by typing the code under Sample boards.
- Clear and New puzzle ask before wiping a game in progress.
- The board sits centred on the screen with the controls at the edges, and Home has more room to breathe.
- Today's board: the same board for everyone for 24 hours, keyed to UTC.
- Optional Game Center: turn it on in Settings to post your time on the daily leaderboards. Each mode has one leaderboard per assist level, so you compete against players who used the same assists; turn assists off for a harder tier. Times with hints aren't posted. Off by default; the app still works entirely offline without it.
