Stelline: Star Logic Puzzles app analytics for October 6

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.
