About

Welcome on the old blog of Bastien Vial-Jaime, puzzlemaker and sudoku competitor.

I no longer publish puzzles on this blog, it having become a bit of a chore over the years; instead I now make weekly videos on the Youtube channel 81 Cells, the one and only channel out there dedicated to sudoku speedsolving, and also do live streams on Twitch.tv/81Cells. I might still publish the occasional puzzle here when I feel like it, but these Youtube and Twitch channels are going to be my main focus for the time being.

On the professional side, I keep contributing to various publications and events such as the yearly French selections for the World Sudoku and Puzzle Championships, and the World Puzzle Federation's Grand Prix. Here are the Sudoku GP round and the Puzzle GP round I authored this year.

 

Several of my puzzles will also be featured in Cracking the Cryptic's next sudoku app, Killer Sudoku, and other projects are currently being discussed.

I provide a wide range of services in the field of puzzlecrafting, with a particular focus on handcrafted sudoku variations of fine quality. My work has been acknowledged many times as been innovative and able to surprise even seasoned players - see for example this study of one of my puzzles by the popular channel Cracking the Cryptic.

Sudoku apps, newspapers and other publications, escape rooms and video games are a few examples of what my puzzles can fit into. If you are looking for a reliable and recognized puzzlemaker, simply contact me at the address bastien.vialjaime@gmail.com.
