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

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