K-Puzzles: Sudoku & Logic

■ 13 logic puzzles, one calm app

K-Puzzles brings together 13 proven logic puzzles from around the world
in a single app. It doesn't start and end with Sudoku — numbers, patterns,
deduction, and visual logic all live together, so you can switch freely
and enjoy fresh brain training every day.

A calm mind, one square at a time.


■ Why K-Puzzles?

● Absolutely no ads
No interstitials, no rewarded ads, no banners. No 30-second ad breaks
the moment you finish a puzzle. Puzzles are all about focus.

● Fully offline — zero data, zero tracking
The app has no internet permission at all. Zero network calls, zero
tracking. It works the same in airplane mode or underground. No ad SDK,
no analytics SDK, no crash-reporting SDK.

● 8 languages
Korean, English, Japanese, Chinese, Hindi, Spanish, Arabic, French.
Selecting Arabic automatically switches the layout to right-to-left.

● Hints that teach, not just tell
These aren't hints that simply hand you the answer. A 4-step progressive
system shows you "where to look" and then proves "why that's the answer."
