Sudoku 12x12 Hard

How to play Sudoku 12x12 on the hard level?

The rules for Sudoku 12x12 are the same as for classic Sudoku. The player must fill in all the empty cells on the game board with numbers from 1 to 12 so that there are no repetitions of numbers in rows, columns, or additional 3x4 sections.

The search for a solution begins by identifying the "weak" cells on the game board. The fewer values a cell can take, the weaker it is. The weakest cells only accept one value, which can be filled in immediately.

For advanced Sudoku, it is necessary to use notes. Notes allow a professional player to keep track of candidate placements on the Sudoku grid.

Which level of Sudoku 12x12 is the hardest?

The difficulty of a 12x12 Sudoku lies in the need to fill in a fairly large number of cells with numbers. The initial number of known digits is small, and their placement often does not allow the use of basic Sudoku techniques. Therefore, advanced strategies are needed to solve such puzzles.

It may not be the most difficult Sudoku, but it still deserves the attention of experienced players. If you find Sudoku not challenging enough, please write to us via email, and we will definitely address it.
