Rules / How to Play
- Grid Size: he grid is typically 9x9, divided into 9 smaller 3x3 sub grids.
- Unique Numbers: You must fill the 9x9 grid with digits from 1 to 9, ensuring that each row, column, and 3x3 subgrid (or "box") contains all digits from 1 to 9 without repetition.
- Outside Clues: Numbers placed outside the grid indicate the first digit(s) in the corresponding row or column when reading from the direction of the clue. For example, a number "5" placed to the left of a row implies that the first cell in that row (from the left) contains the number 5.
- No Inside Clues: Some Outside Sudoku puzzles may completely omit clues inside the grid, relying solely on the outside clues. However, other variations might include both internal and external clues.
