Description
Carol Vorderman's Sudoku puts classic number logic on the PSP, offering dozens of puzzles across multiple difficulty tiers. Players pencil-in possibilities, use hints sparingly, and race the clock in timed challenges or relax with slower puzzle modes. The portable format emphasizes pick-up-and-play sessions, satisfying methodical thinking and pattern recognition while retaining a clean, no-frills presentation that feels nostalgic for handheld puzzle fans. Difficulty ramps up to test veterans with fewer assists, rewarding careful deduction rather than brute force. Ideal for commuters and logic fans seeking compact, focused mental exercise.

We're finalizing the process to publish on the Microsoft Store soon, after which this warning will no longer appear. - Android: Install the KhoGameHub app → tap Open in App to play directly.
- Linux: Download KhoGame Linux Launcher (Ubuntu/Debian/Arch), run
chmod +x khogame-launcher && ./khogame-launcher, then click Play on PC again. - Controls: Plug in a gamepad and it works immediately. To remap buttons → open PPSSPP → Settings → Controls.

🛠️ Troubleshooting
- "Could not load game" error: Click the Clear Cache button on the game page to remove the corrupted cache. This usually happens when the ROM download was interrupted or the downloaded file got corrupted. If it still doesn't fix it, you can go to the KhoGameHub Launcher's install folder, find the corrupted ROM cache file, and delete it manually.
- New features not working after a launcher update: Open the Launcher and check you're on the latest version; if not, re-download the latest build from the server to fully update the hybrid app's features.
