🧩 Fill the grid so every row, column & box has no repeats.

📜 The Navakosh was built to seal runaway number magic. Asura-name guardians test each floor because every solved grid locks their chaos back into place.

❤️ Wrong number = lose a heart. Run ends at zero.

⚡ Correct cells charge mana. Spend it on relic powers.

🎁 Clear a floor → pick a relic. Go deeper for loot & bosses.

👑 Floor 100 hides the golden trial. Beat it and the dungeon knows you as a Sudoku Legend.

📦 Boss floors add killer cages: marked cells form extra no-repeat sum traps.
