Spark Sudoku # 8
- Details
Recently I noticed with stupefaction that the last time I published Spark Sudoku was in 2020. This is the problem we face when we have a lot different puzzles. Some puzzles are less frequent than others. In order to amend, I offer you two Spark Sudoku this week. The peculiarity of this puzzle is that the grid could take the shape of a star with 5,6,7 or even 8 points. At first, this sudoku looks strange but it has columns, row s and regions. You need to use the numbers 1 to 8. You will quickly fall in love with this kind of Sudoku.
The two puzzles are hexagram (six-pointed star).

No commentsTrain Track # 12
- Details

During this time of year, many people go on holiday. Quite a few decide to get away from it all and explore new places. The train is a brilliant way to see the country. To keep with the theme, here are two multi-train puzzles, which are actually four 8x8 grids linked together. You need to start from the arrow to recreate the railway route. The clues around the grid indicate how many squares there are in the column or row through which the railway runs. Even if it’s not the holidays, this game will help you get away from it all.

Binairo # 2
- Details
One of the latest puzzles that I have added recently is the Binairo. In fact I have produced Binairo since 2012. This is only this year that I have decided to add it on my web site. I do not know why it was so long. Maybe I believe it is because I have a lot of different puzzles, and each year I add new ones. The rules are simple:
1) Each line and column must have the same number of 0 and 1.
2) No more than two consecutive numbers in a line or column could be placed.
3) A line must be different from all the other lines and a column must be different from all the other columns
I present to you two grids: the first is 10x10 and the second is 12x12. Have fun !

Tertradecagon Sudoku # 2
- Details
Tetradecagon Sudoku is played on a grid with 14 sides (a polygon called a tetradecagon). There are therefore 14 columns when moving clockwise and 14 more when moving counterclockwise. Each column contains the numbers 1 through 12. The regions can be identical in shape, as in the second, or irregular, as in the first one. A column starts at one of the grid’s sides and continues, after six squares, to the center; the column then bounces off the adjacent square to reach another side of the grid. The column thus resembles a bird in flight. That’s all there is to it—enjoy!
