This new grid, published on Friday, 3rd January 2026, follows the newspaper's long-standing tradition of providing a daily mental workout for readers seeking to sharpen their minds.
The Intricacies of Expert-Level Sudoku
Expert Sudoku puzzles, like number 7163, are designed to push solvers beyond basic elimination techniques. They require a deep understanding of advanced strategies such as X-Wings, Swordfish, and XY-Chains. The puzzle demands meticulous attention to detail and the ability to spot complex patterns within the 9x9 grid. The difficulty level is set to 'expert', indicating that it is intended for seasoned players who are comfortable with the most demanding logical conundrums.
Regular engagement with puzzles of this calibre is widely recognised by cognitive scientists as a beneficial activity for maintaining mental agility. It exercises the brain's logical reasoning and pattern recognition faculties, providing a structured form of problem-solving that can be both meditative and intensely stimulating.
A Staple of British Puzzle Culture
The Guardian's puzzle section, which includes this Sudoku, forms a key part of the newspaper's lifestyle and culture offering. It provides a consistent and reliable source of intellectual entertainment for millions. The publication of puzzle #7163 on a Friday morning offers readers a perfect weekend brainteaser to ponder over a leisurely cup of tea or coffee.
For those attempting the expert challenge, the process typically involves a methodical approach. Solvers must fill the grid so that every row, every column, and every 3x3 box contains the digits 1 to 9 exactly once. The starting grid provides a limited number of clues, and from there, pure logic must guide the way to the single, unique solution.

It requires no mathematical ability, just clear, deductive reasoning. Puzzles like #7163 offer a satisfying sense of accomplishment upon completion, a testament to the solver's patience and skill.
Completing an expert-level grid is no small feat. It often involves:
- Careful pencil-marking of candidate numbers.

- Applying advanced techniques to break through logical impasses.
- Maintaining patience and a systematic approach throughout.
