Super Sudoku Three Dimensions no 2 (follow up)
- Details
Finally, a winner! A long time ago (in February 2017, see the link contest), I had the idea to create a contest. So I posted a three-dimensional Super Sudoku puzzle, offering a book to the first person to submit the correct solution. I hadn’t realized just how much effort this task would require; for several years, I didn’t receive a single correct answer. Sometimes, I received criticism for not publishing the answer. I was tempted several times to end the contest without a winner. But last month, I received a correct answer. I therefore declare the official winner: Mr. Giuliano Cavazzonni of Castelfranco Emilia, Italy. I’d like to congratulate Cavazzonni for the diligence and perseverance he demonstrated in completing this puzzle. Here is his solution.
I congratulate Mr. Cavazzonni once again—what an achievement!
I’ve learned from this experience never to hold another contest with puzzles that require so much dedication. This fall, I plan to hold another contest with puzzles that are more reasonable to complete (surely taking less than 9 years to find a winner),

News !
A few months ago, I posted an online app on my website for playing Yakazu. I wanted to add an online Suguru app as well. I’ve improved the interface a bit (I plan to revamp my online Yakazu app one of these days to incorporate these features).
My app contains over 200 games in 5 different sizes: 6x4, 6x6, 7x7, as well as larger grids like 13x8 and even giant 15x15 Suguru puzzles.
The interface was designed to be simple and, above all, free of annoyances like ads, animations, pop-ups, etc.
The larger grids are optimized for play on either a computer or a tablet. On a phone, the user experience will be better with the smaller grid sizes.
I hope this page is a success; please feel free to share your suggestions with me.
The link is : Online Suguru. Please note that the online puzzle can be accessed from the menu under the “Online Puzzles” section.

Try to play as a detective with the codeword puzzle. In a grid each letter, each was replaced by a number. Fortunately, a word is already shown, and also some letters are given. You just have to use your mind by deduction to recreate the grid. Here are two puzzles for you.

Jigsaw Sudoku # 18
- Details
Last week I presented you the Killer Sudoku, now offer you another sudoku variation : the jigsaw sudoku. Its peculiarity is that its regions have irregular shapes instead of being gentle 3 × 3 squares. It allows more flexibility for creating sudoku of different sizes, like 8x8,10x10, etc., because the irregular regions fit well in any size grid. I present you with two different sizes : 5x5 and 6x6, use numbers 1 to 5 in the first case and 1 to 6 in the second case.

I want to present to you my first book of 9x9 jigsaw sudoku titled Jigsaw Sudoku Challenge vol. 1. As you could notice, the cover of this book was in my earlier period (the cover was made with all my naivety and lack of skill) but the puzzles are great.
