Sudoria: Sudoku Puzzle Journey

Sudoria is a proper Sudoku game that gently makes you better, set in a magical starlit library.

■ Gram, your gentle teacher
Stuck? Tap "Hint" and Gram highlights the next move — and explains WHY the number goes there. You don't just copy answers; you actually learn how to solve.

■ A journey of 200 stages
From learning the rules in Chapter 1 to master techniques in Chapter 8: naked singles, hidden singles, locked candidates, naked pairs, hidden pairs, X-Wing and more — one small step at a time. The scenery and Gram's expressions change as you travel.

■ Endless Challenge
Five mistakes and the run is over. Everyone starts on the same fair curve — how many puzzles can you clear in a row? Beat your best record and share it with friends.

■ Daily Puzzle
One puzzle a day — the same board for players all over the world.

■ Made to be comfortable
- Every puzzle has exactly one solution
- Difficulty rises gently, from your first grid to demon-level boards
- Notes, auto-notes, undo, mistake check
- Timer, mistake counter, star ratings
- Fully playable offline, no login required
- Ads never interrupt your game (top banner only, no forced videos)

Cozy on the outside, serious Sudoku on the inside. Whether it's your first grid or your thousandth, level up happily with Gram.
