Suguru ; A new book : Suguru Challenge vol 10

Details: Published: 19 March 2026

Here it is, hot off the press: my latest book: Suguru Challenge Vol. 10.

The first time I published a book about the Sugurus was in 2016, and I never imagined that this puzzle would become so popular that, ten years later, I’d be publishing a tenth volume in the series. I remember discovering this game during a trip to England with my family in 2015. I was on the Tube (the London subway) and saw a young woman standing there with a magazine, frantically playing games. I wanted to know what game it was, so I approached her discreetly to see what kind of games could cause such excitement. I was far too shy to speak to her, so I could barely see what was inside the magazine, except that it contained grids of various sizes. Now I know it’s the excellent British magazine Suguru by Puzzler. So, on my last day before leaving, I was at the train station scouring the magazine stands to see what kind of puzzles it might be—my only clue was that the cover was blue. Finally, I found a magazine (though with a red cover) that featured this puzzle, which was completely unknown to me. I decided to buy it. When I went to the register, I paid the price, but since I was confusing pounds and pence, I laid out several coins on the counter to pay until I realized my mistake. That’s when I witnessed the legendary British composure, as the cashier stoically waited while the line behind me grew longer. Once I got home, I was immediately captivated by this game and decided to add it to my repertoire. I experimented and managed to create grids of all sizes. From small 4x56 grids to giant 20x20 grids.

This book, like all nine others in the series, contains 251 puzzles in a variety of sizes (from 4x6 to 20x20) that no other book can offer you. Here are three puzzles; judge for yourself.
