# Help Center Welcome to the Sudoku Help Center. This page covers the features currently available in the app, based on the live product flow in the project. If you cannot find the answer you need, please use the **Feedback** entry in **Settings** to contact support. ## Frequently Asked Questions ### 1. How do I start a puzzle? From the Home screen, you have 3 ways to begin: 1. Tap **Quick Start** to open a puzzle right away. 2. Tap a difficulty under **Play by Difficulty**: - **Easy** - **Medium** - **Hard** - **Expert** 3. Tap **Daily Challenge** to open today's puzzle. ### 2. What does Quick Start do? **Quick Start** tries to open a standard puzzle immediately. In the current project flow, Quick Start prefers a **Medium** puzzle first. If no Medium puzzle is available, the app will fall back to another available difficulty automatically. ### 3. How does Continue Puzzle work? If you leave a puzzle unfinished, the Home screen can show a **Continue Puzzle** card. That card includes: - the current puzzle type or difficulty - your elapsed time - your current progress Tap **Continue** to resume the same session. Tap **New Puzzle** if you want to leave that puzzle and start a different standard puzzle. ### 4. What is Daily Challenge? **Daily Challenge** is the daily puzzle entry on the Home screen. Its button text changes with your current state: - **Start Challenge** if today's puzzle has not been started - **Continue Challenge** if today's challenge is already in progress - **Completed Today** if you already finished today's challenge - **Unavailable Today** if today's daily puzzle is not available in the current build If the app shows **Daily Challenge Unavailable**, please update the app and try again. ### 5. What actions are available during a game? The current game screen includes: - **Undo** - **Redo** - **Auto Notes** - **Hint** - number input **1-9** - **Delete** - bottom note toggles **1-9** - **Pause** - **Game Settings** ### 6. How do Auto Notes and bottom notes work? The current project has 2 note-related actions: - **Auto Notes** - bottom note buttons **1-9** When **Auto Notes** is enabled, the app enters its automatic notes mode. You can also tap the note numbers along the bottom bar to toggle notes for the currently selected empty cell. If **Auto Notes** is turned off after notes already exist, the app may clear the current notes state as part of leaving that mode. ### 7. How do Hints work in the current app? Tap **Hint** during a puzzle to request a suggested move. In the current project behavior: - the app opens a hint sheet instead of filling the number immediately - the sheet shows a title and a short explanation - if the app finds a wrong value that needs correction, the hint may point to that incorrect cell - you can choose **Not Now** or **Apply Hint** **Not Now** closes the hint sheet without placing a number. **Apply Hint** fills the recommended value into the recommended cell. ### 8. Is there a free limit on hints? The current project code uses a hint usage limit internally and may show the membership screen after the free usage limit is reached. Because this limit can change with product configuration, the safest user-facing description is: - free hint usage is limited - after the free limit is reached, the app may prompt you to unlock **Pro** ### 9. What happens when I make a mistake? The game keeps track of your **mistake count**, which is shown near the top of the game screen. If you enter an incorrect number, the app can: - increase the mistake count - keep the puzzle playable - use that state in later hint suggestions ### 10. Can I pause a puzzle? Yes. Tap the **Pause** button at the top of the game screen. In the current project, the pause dialog shows: - **Resume** - **Restart** **Resume** continues the current session. **Restart** starts the same puzzle again from the beginning. ### 11. What can I change in Game Settings? From the game screen, tap the settings icon to open **Game Settings**. The current project exposes these settings: - **Show Timer** - **Sound** - **Haptics** - **Highlight Related Areas** - **Highlight Same Numbers** The app also contains a **Step-By-Step Hints** setting in code, but it is currently hidden in the active settings screen. ### 12. What appears in the main Settings screen? From the Home screen, tap the top-right settings button to open **Settings**. The current Settings screen includes: - **Share with Friends** - **Rate Us** - **Feedback** - **Privacy Policy** - **Terms of Service** - **Version** It also includes a membership entry card that opens the Pro page. ### 13. What is Pro in the current project? The current project is built around a **one-time Pro unlock**, not an auto-renewing subscription flow. On the Pro screen, the current benefit copy is: - **Get full access** - **100% Ad-free** - **Access future features** The purchase button copy is: - **Unlock once, own forever** If Pro is already active, the screen changes to the unlocked state. ### 14. How do I restore purchases? Open the Pro screen and tap **Restore Purchases**. In the current project behavior: - restore does not purchase again - it asks Apple to verify previous ownership - if no matching purchase is found, the app shows a restore-not-found message If Pro still appears locked after restoring, try: 1. Make sure your network connection is working. 2. Fully close the app and reopen it. 3. Open the Pro page and tap **Restore Purchases** again. 4. If the issue continues, use **Settings > Feedback** to contact support. ### 15. How do I contact support? In the current project, the support contact entry is: - **Settings > Feedback** That action opens the Mail app using the app's configured feedback email address. When contacting support, it helps to include: - your device model - your iOS version - your app version - what screen you were on - what you expected to happen - screenshots if available ### 16. Where are the Privacy Policy and Terms of Service? In the current project, both are opened from: - **Settings > Privacy Policy** - **Settings > Terms of Service** These links are driven by the app's configured URLs in the build. ### 17. Why does the Home screen sometimes show Daily, and sometimes Continue Puzzle? The Home screen supports both: - a most recent unfinished session - a separate daily challenge state So it is normal to see: - **Continue Puzzle** for your latest unfinished standard or daily session - **Daily Challenge** as its own card with today's challenge status **Last updated: May 20, 2026** For the site tree, see the [root Markdown](https://slashpage.com/sudoku.md).
