数独规则
填写9×9网格，使每行、每列以及九个3×3方格中均包含1到9的所有数字各一次。
1.Each row must contain 1–9 with no repeats
2.Each column must contain 1–9 with no repeats
3.Each 3×3 box must contain 1–9 with no repeats
4.Use arrow keys to navigate cells
5.Blue highlight = related cells (same row/col/box)
6.Green cells = solved by the algorithm
Solving Tips
•Start with rows/columns/boxes that already have the most numbers filled in.
•Look for cells where only one digit is possible — this is called a 'naked single'.
•If a digit can only appear in one cell within a row, column, or box, place it there.
•Use pencil marks to track possible digits in each cell.
•Can't crack it? Hit Solve — the backtracking algorithm never fails!
