Apa itu Sudoku?
Fill a 9x9 grid with digits 1-9 without repetition in any row, column, or subgrid. Utilize real-time error checking and note-taking for advanced deduction.

Cara bermain
Solving at a Master level depends on "Candidate Elimination Logic." Instead of searching for where a number can go, look for where it must go. Utilize the "Naked Pair" technique: if two cells in a block can only contain the same two numbers, you can eliminate those numbers from all other cells in that block. A pro strategy is to identify "Locked Candidates"—situations where a number in a row also belongs to a specific 3x3 subgrid, allowing you to clear potential spots in adjacent columns.
