Sudoku # 5 Diagonal
- Details
Here are some X sudokus, also known as diagonal sudokus. Just like as a classic sudoku, you must fill each column, row, and region with the numbers 1 to 9, but in addition, the two diagonals, the ones with gray squares, must also contain the numbers 1 to 9. This additional constraint can both help or complicate things a little. Here are three waiting for you.

First and foremost, I would like to wish you a happy new year in 2026! May it be filled with health, love, joy, and a few puzzles to entertain you. To get 2026 off to a good start, I suggest you try hanidokus. I don't usually publish these puzzles because I have several in my bag, so it's a bit neglected (as I plan to publish new puzzles this year, this phenomenon is likely to increase). It's a shame, though, because this puzzles is just as captivating as the others.
You have to enter a series of consecutive numbers (between 1 and 9) in each row and diagonal, depending on the length of the row or one of the diagonals. Thus, the center row containing 9 hexagons will have the numbers 1 to 9. For a row consisting of six hexagons, the possible combinations would be 1,2,3,4,5,6, 2,3,4,5,6,7, up to 4,5,6,7,8,9. This rule also applies to diagonals, so a hexagon that is at the intersection of a row and two diagonals must respect the shortest length.

Hidoku # 20
- Details
I would like to wish you all happy holidays. To end the year on a high note, here are two types of hidoku with similarities. Both consist of two more or less circular shapes that are paired together. The first is a grid composed of two octagons side by side, while the second looks more like two geometric donuts side by side. Both puzzles have squares, rectangles, or diamonds cells. In the second puzzle, there are lines in the center that allow you to connect the two cells.
Finally, you have to connect all the cells by making a path that runs through the entire grid. The two gray squares indicate the start and end of the path.
Okay, enough talk, have fun!

Snowflake Puzzle # 5
- Details
To get into the spirit of this time of year, I suggest you try Snowflake Puzzles. This is one of the puzzles I added to my repertoire this year. Snowflake Puzzles is a puzzle that requires logic and basic arithmetic skills (knowing how to add three numbers less than 6). You have to write a number from 1 to 6 in the white hexagons so that the total of the three hexagons pointing to the central hexagon (the gray one) is the same as the number indicated in that central hexagon. In addition, the hexagons around a central hexagon must have different numbers. The point is that a hexagon can orbit several central hexagons.
Don't wait any longer! Take on the snowflake puzzle challenge!

Hyper Sudoku 3d # 22
- Details
This year, I published a book on 3D Hyper Sudoku called: Hyper Sudoku 3D. I was the one who invented this type of sudoku. First and foremost, a 3D sudoku is a sudoku that is written on a cube, with all the characteristics of a classic sudoku, i.e., each column, row, and region must all have different numbers. What is confusing is that a row or column starts on one side of the cube and ends on another adjacent side of the cube. This already existed, but my humble contribution was to arrange two or even three cubes together. The junction between two sides of two different cubes forms a new column or row. This can be confusing, but at the same time it can be a lot of fun for Sudoku fans. Here are two versions on 4x4x4 cubes (you must use the numbers 1 to 8), the first with two cubes and the other with three cubes stacked in a pyramid.
