About Grid Wiz
Our Aim
Grid Wiz was created with a simple goal: to make high quality sudoku collections in beautiful formats.
One of the most common frustrations with sudoku books is inconsistent difficulty — puzzles labeled “easy” that feel hard, or collections that jump unpredictably between levels, or puzzles with more than one solution.
To address this we classify our puzzles carefully by solving every puzzle first so we can base our ratings on the solving techniques required to complete each puzzle, combined with other factors that affect effort and flow.
We also provide you with free sample puzzles and technique descriptions so that you can try for yourself if you're not sure what difficulty suits you.
Alongside puzzle quality, we care deeply about presentation. Our books are designed to be:
- clean and uncluttered
- comfortable to solve
- easy to carry and return to
As a small independent publisher, the most realistic way for us to bring you our puzzles is using Amazon self-publishing. This does mean we have limited control over the physical characteristics of the books. We are generally satisfied with the print quality and believe this pathway is the best way to bring you high quality books at a reasonable price. However, on occasion books can arrive damaged or with other printing defects, in which case please approach Amazon customer service who should help you resolve the issue.
