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
1.
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
