Difficult Sudoku 6x6 Tips for Solving

Among 6x6 sudoku puzzles, this is a challenging level, although there are even more challenging puzzles in general sudoku. We recommend reading the brief rules of the game:

1. The game grid only accepts numbers from 1 to 6.
2. Repeats are not allowed in columns.
3. No digit repeats are allowed in rows.
4. Duplicates are not permitted in the 2 by 3 additional areas.

We suggest starting either from the beginning (with the number 1) or from the end (with the number 6) and systematically filling in a specific digit throughout the entire game grid. Continue until all cells are filled.
