## Description

Runline is a compartment-based logic puzzle: a grid where some cells are permanently blacked out, and the white cells left behind form short runs called compartments. Fill every white cell with a digit so two rules hold everywhere at once — and the grid clicks into place.<br><br>THE TWO RULES<br>1. No repeats. Just like a number grid you already know, no digit may repeat anywhere in the same row or the same column among the white cells — even across different compartments.<br>2. Every compartment is a straight. Each unbroken run of white cells, whether it&#39;s running across a row or down a column, must end up holding a set of consecutive digits in any order. A four-cell compartment might land on 3-4-5-6 in whatever arrangement you like — but never with a gap, and never with a repeat.<br><br>Line up both rules across the whole board and the puzzle is solved.<br><br>PICK YOUR GRID<br>- 6x6 — a compact board with a couple of starting digits to anchor your reasoning.<br>- 7x7 — the sweet spot: enough given digits to trust, enough grid to think.<br>- 8x8 — a full board with fewer givens, built for players who want to work for it.<br><br>EVERY PUZZLE IS GENERATED, EVERY PUZZLE IS FAIR<br>Runline builds a fresh, valid board behind the scenes for every new game and checks that the digits you&#39;re given are actually enough to solve it before handing it to you — no guessing games, no unsolvable grids.<br><br>SEE THE STRUCTURE, NOT JUST THE NUMBERS<br>Tap any open cell and Runline highlights exactly which cells it has to form a straight with — the live compartment it belongs to, both across and down — so you can reason about a run without losing track of where it starts and ends. A warm parchment palette, deep graphite ink, and a signal-red accent keep the board easy to read at a glance.<br><br>STAY ON TRACK<br>- Live violation highlighting flags a repeated digit in red the moment it happens, and flags a compartment that&#39;s full but not a proper straight in amber — two different problems, two different colors.<br>- A running timer and mistake counter track how clean your solve is.<br>- Stuck? Hint reveals one correct cell — mistakes and hints are both tracked, never punished.<br><br>LEARN AT YOUR OWN PACE<br>The Learn tab walks through both rules in plain language and includes a quick &quot;is this a straight?&quot; practice puzzle: look at a handful of digits pulled from one compartment, decide whether they form a valid run, and build your intuition before tackling a full grid.<br><br>TRACK YOUR PROGRESS<br>Runline quietly remembers your best time per grid size, your current and best win streaks, and a shelf of awards that unlock as you keep solving — all stored right on your device.<br><br>FULLY OFFLINE, FULLY PRIVATE<br>- No internet permission — the app genuinely cannot go online.<br>- No ads, no trackers, no analytics, no third-party SDKs.<br>- No account, no sign-up, no personal data collected.<br>- Every board, every save, every best time stays on your phone.<br><br>No sound, no clutter, no pressure — just a clean grid, two honest rules, and a line that&#39;s yours to finish.<br><br>Pick a size. Read the compartments. Run the line.
