Sudoku

Set up sudoku on this computer

Puzzle Difficulty dialog showing SE rating and required sudoku solving techniques.
Difficulty dialog: SE rating and the solving techniques required for the selected sudoku puzzle. Sudoku C++ resources/screenshots from darkstar79/sudoku (GPL-3.0).

Choose the Sudoku C++ asset that matches this computer, install from GitHub Releases, and prove one local game before you chase difficulties.

Windows wants the win64 exe. Apple silicon wants the arm64 source build. Intel Macs want the intel source build. Linux x86_64 wants the AppImage. No winget or brew cask was verified.

Identify the OS

Write the OS version on the machine ticket beside the chosen filename. Mixing Flatpak and AppImage without notes creates duplicate uninstalls later.

  • Windows 64-bit: run the win64 exe installer
  • macOS: source tree to Applications
  • Linux: chmod +x AppImage

Windows path

Download Sudoku-*-win64.exe, run the installer, then open Sudoku C++. Detail: Windows.

macOS path

Prefer arm64 source build on Apple silicon. Use intel source build on Intel Macs. Detail: macOS.

Linux path

Prefer AppImage from the same tag as Windows. Flatpak alternate: Flatpak. AppImage guide: Linux.

Prove the first game

Pick easy, clear a few cells, flag one mine. Timer starts on first release. First run: first run. Checklist: installed.

Document the update door

Return to the same Releases filename for the next bump. Update guide: update uninstall. Safe download: download safe.

When this computer cannot install

Locked school images may block exe installer or AppImage execute bits. Keep a browser board as temporary fallback, then install the client when you regain rights. Comparison: vs Microsoft Sudoku.

Cell Quill publishes the chooser. Upstream remains darkstar79/sudoku. Prefer Qt6 assets when the tag ships both series so labs stay on one family.

Shared desk checklist

  • One GitHub Releases URL on the ticket
  • One Qt6 asset name for this OS
  • One proven easy game after every reimage

Return to darkstar79/sudoku Releases when SmartScreen or Gatekeeper interrupts. Do not accept a second portal.

Lab and travel notes

Shared labs should treat the filename as part of the machine image. After every reimage, open GitHub Releases again, confirm the Qt6 asset still exists on the tag you pinned, and prove one short local game.

Travel laptops benefit from the same boring checklist: one installer door, one extract or Applications path, one note for the next bump.

  • Family PCs may keep Store Sudoku beside the client
  • Command-line users may add Flatpak after Releases works once
  • Document UNVERIFIED where a package command was not run here

Cell Quill publishes independent install guidance. Upstream the client remains GPL-3.0 at darkstar79/sudoku. Prefer phrase-first puzzle language in titles.

When assets change

When a release drops an OS asset, pause imaging work and re-check the live list. Prefer the next tag that restores your primary filename rather than inventing a new download brand.

Keyboard play, dark difficulties, and custom puzzles are comfort settings. They come after a proven game on easy. First-hour checklists exist so desks do not chase Options menus too early.

Filename discipline

Write the exact the client asset name beside the OS version before you image a lab. Prefer Qt6 when the tag ships both series so Windows zip desks match macOS source tree and Linux AppImage desks.

  • Sudoku-*-win64.exe on Windows
  • (no macOS release installer) on Apple silicon
  • Sudoku-*-x86_64.AppImage on Linux

No winget id and no Homebrew cask were found on this review date. Flatpak remain UNVERIFIED alternates documented upstream. Prefer Releases first.

After the first proven game

Only after one easy game works should you open Options for difficulties or try a custom puzzle. First hour: installed. First run: first run. Pencil marks: keyboard and difficulties.

Keep Microsoft Sudoku only if achievements still matter. Switch notes: switch. Comparison: vs Microsoft Sudoku. Safe download: download safe.

Cell Quill maps filenames. Upstream the client remains GPL-3.0 at darkstar79/sudoku. Refuse Softonic-style mirrors even when a first launch is blocked.

Refuse renamed portals

If a site renames a puzzle setup for a search ranking, stop. Match the filename on GitHub Releases for darkstar79/sudoku instead. Home install panel: home. Releases map: releases.

  • Type the GitHub URL yourself
  • Confirm the tag still lists your Qt6 asset
  • Prove one easy game before difficulties
