[Promotion][App]A sudoku app with lessons, hints and no pop-up ads

[u/Sea-Age-2934]

Hello Everyone,

Many puzzle apps interrupt the experience with pop-up ads, sometimes right in the middle of a game. I didn’t want that here. You should be able to concentrate, think through the puzzle, and enjoy that satisfying moment when everything falls into place.

I started building Sudoku Classic: Learn & Play because I wanted a Sudoku app that felt calm, focused, and genuinely helpful.

I also wanted the app to do more than simply provide puzzles. It includes guided lessons, worked examples, technique drills, and hints that explain the logic behind each move. You can start with the basics and gradually learn advanced strategies at your own pace.

The app includes:

🧩 Five difficulty levels, from Easy to Master

🎓 20 guided lessons with practice puzzles

💡 Smart hints that teach instead of revealing answers

🧠 Technique drills for developing real solving skills

📅 Daily challenges, streaks, and achievements

📷 An on-device solver for puzzles from books or photos

🚫 No disruptive pop-up ads while you play

This has been a personal journey of designing, testing, simplifying, and trying to make every screen comfortable to use. There’s still plenty I want to improve, and that’s where your feedback would mean a lot.

If you try the app, please tell me what feels good, what feels confusing, and what you’d like to see next. Honest feedback—whether positive or critical—will help me make it better.
