JOURNEY

Your puzzles become a journey.

Every puzzle you solve moves you along a route around the world — 12 regions, 20 stages each. Difficulty grows by real solving techniques, not random number counts.

COLLECT

Solve. Collect. Color.

Landmark stages award postcards as line art. Keep earning stars in a region and each postcard fills with color — up to a gold-foil finish.

Before you ask.

More answers — including backup and device transfer — on the support page.

Yes. Puzzle generation and your records are handled on device, so airplane mode changes nothing.

Which devices are supported?

Does progress sync between iOS and Android?

No. There is no account, so nothing syncs automatically. Move a backup file across instead.

Can I move my progress to a new phone?

Export a backup in Settings and import it on the new device. There is no automatic backup, so export before you switch.

Do puzzles always have one solution?

Yes. Every puzzle is verified for a unique solution when it is generated.

Where do I report a problem?

Email us at h1.soft.x001@gmail.com.
