Find gameplay instructions and troubleshooting below. If the issue continues, contact support using the details at the bottom of this page.
How to play
- Compare the START and GOAL four-by-four grids.
- Arrange the available operations—such as rotation, flipping, movement, and coloring—in the correct order.
- Clear the puzzle by making the result match the GOAL.
ENDLESS MODE presents puzzles continuously. STAGE MODE lets you work through all 300 puzzles in order. If you get stuck, watch an optional rewarded ad to use a hint. After purchasing Remove Ads, hints are available without watching video ads.
Frequently asked questions
Where is my progress saved?
Game progress and settings are generally stored on your device. They are not saved on a server independently operated by the Developer.
Can I transfer progress to a new iPhone?
The App has no proprietary account or cloud-sync system. Apple’s backup or device-migration features may transfer the data, but transfer is not guaranteed. Follow Apple’s backup guidance before erasing your old device.
How do I purchase Remove Ads?
Select Remove Ads from Settings or the purchase prompt in the App, then follow the App Store purchase screen. It is a non-consumable in-app purchase.
How do I restore my purchase?
Sign in to the App Store with the Apple Account used for purchase and select Restore Purchases in the App. If it is not restored, check the connection and Apple Account, then restart the App.
Why is a hint ad unavailable?
An ad may be unavailable because of connectivity, ad inventory, region, consent choices, or network restrictions. Check your connection, wait a little, and restart the App. The App will not ask for payment or personal data merely because an ad is unavailable.
Why do I still see ads after purchase?
Select Restore Purchases using the same Apple Account and restart the App. If the issue continues, contact support with the purchase date and affected screen. Do not send a full receipt or payment details.
Why is there no sound?
Check iPhone volume, Silent Mode, Focus, Bluetooth connections, and the in-app sound settings. You can also close other audio apps and restart Pattern Line.
How do I change the language?
Select Japanese or English in the App’s settings. If it does not update, close and reopen the App.
