About the Game

One purchase. Every puzzle. Zero noise.

Sudoku Atlas is a premium, distraction-free Sudoku app built for people who
actually love the puzzle. There are no ads, no in-app purchases, no accounts,
and no tracking. The app never touches the network. You pay once and own the
whole thing, forever, fully offline.

From 4×4 to 25×25

Most Sudoku apps give you one grid size. Sudoku Atlas gives you five, spanning
a huge difficulty range:
  • Warm up on tiny 4×4 and 6×6 boards.
  • Settle into the classic 9×9.
  • Push into 16×16 for a serious session.
  • Take on the sprawling 25×25 when you want to disappear into a puzzle for an
    hour.
Every board is generated deterministically from a seed, so a puzzle always has
exactly one solution, and the same seed gives you genuinely the same puzzle
every time.

Built for focus

  • Clean, minimalist interface that stays out of your way.
  • Pencil marks, one-tap undo and redo, and hints when you want them. Never
    forced.
  • Your progress, settings, and statistics live entirely on your device.
  • No timers shouting at you. Play fast, or don't.

Play it your way

  • Mouse, keyboard, or touch. Each one on its own is enough to play the
    entire game. Full keyboard control (arrow keys, number entry, pencil mode,
    undo, redo, hints) for desktop purists, and complete touch control for 2-in-1s,
    touch monitors, and Steam Deck.
  • High-contrast theme for low-vision play.
  • Colorblind-friendly by design. Color is never the only signal. Shapes,
    borders, and underlines carry the same information.
  • Respects your system text size and ships a full screen-reader label
    tree.

Private by principle

Sudoku Atlas makes zero network requests. There is no analytics, no advertising,
and no crash reporting. Nothing you do in the app leaves your device, because
there is nowhere for it to go.

Who it's for

Whether you solve one 9×9 with your morning coffee or lose an evening to a
25×25, Sudoku Atlas is the Sudoku app you keep coming back to. Buy it once and
it never asks you for anything again.
