sudoku in 3D

Do you know sudoku?

Sudoku (originally called "number place"), is a logic-based, combinatorial number-placement puzzle. A typical sudoku puzzle consists of nine rows and nine columns in a grid. Some of the squares are pre-filled with one number each; others have blank space to be filled in by the player.









The aim of the game is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids that compose the grid contains all of the digits from 1 to 9, but each number only once.

"I was lucky enough to try it out on an Innovation Exhibition and I really liked it. It was a good feeling that although only one side, but I was able to put it first. I'd love to play with my own."

"I see this first for the first time now, and I think it's a very good game that I would like to play with during travelling on the train or while waiting."

"It's cool and even better than the traditional paper-based version."

"Modern, can be reused many times, anywhere and anytime I can continue where I last stopped."

"How come that this was not invented before?!"

"I first played sodoku 1 or 2 years ago and since that I often challenge myself with that. I’m curious about this version, I like the idea. If it is available I would definitely want one."

"It seems like something I'd like to spend time with during a boring lecture at school or on the train."

"The 3D version is good idea! I really like it."

Peter Bagi

I am PETER BAGI, the inventor of su3Doku, thesudokucube.

The story of thesudokucube began 10 years ago, in 2008.

We spoke about old toys. I remembered a tili-toli puzzle sergeant Pityke on it. It was one of the best logic games in the '90s. Of its many variants I can recall this very one, which had a policeman and a dog on. Then I imagined how "sergeant Pityke" would have been in "hedgehog" with others. Can you imagine? ... the "tili-toli" puzzle in 3 dimensions. In "hedgehog".

Those days I often spent time in front of the computer playing sudoku online I'm not a pro, but I like it because it make me think. In the simplest version you only need to figure out which number is missing. In a more complicated version you have to think ahead a few steps. There are millions of versions, but there is always only one solution.

The sergeant Pityke tili-toli puzzle consisted of a few small squares. In the traditional sudoku game, 9 numbers must be placed in a 9x9 square divided into 3x3 sub-areas. If the puzzle consisted of 9 squares, then it would correspond to such a 3x3 subfield. Sergeant Pityke in "hedgehog" is a cube with sides 3x3. The idea obviusly came to my mind- what if we write numbers on the squares while adapting the rules of sudoku? Is that possible? I do not know...

... but I imagined it.

This was the beginning.
