Funny how things turn out sometime. :-)

Turns out that about the same time as I invented Sudoku 10, some other persons also came up with the same idea. *smile* These persons called their game ClueLess Explosion.

Looking at the games they really do look alike. Sudoku 10 and ClueLess Explosion seem to be the same game, with only differences being that they have different layouts and Sudoku 10 having clues in the 10th game.

Looking more in detail on these differences though, I would say that Sudoku 10 is probably easier for non-experienced to intermediate Sudoku players since there are clues in all ten games and the 10th game is more clearly outlined (especially with many numbers filled in).

ClueLess Explosion is probably a bit more difficult, with no clues in the squares of the 10th game. But that depends on the positioning of the existing clues.

I think both versions can be both as easy and as hard as the other. They both need to be played on two levels. So in many ways they really are the same. The end result is definately the same, but the way to get there is slightly different.

There was also a similar game developed by the same persons called ClueLess Special.

There is a difference however between Sudoku 10 and ClueLess Explosion on one side, and ClueLess Special on the other side, and this is that ClueLess Special is more easy to solve simply because all the clue-less squares are joined in complete sections.

Isn't it funny how things turn out when going global. *smile* This just proves that an idea is seldom unique!

I suppose the reason why I didn't find these games before was the name of the game, "ClueLess Explosion", not the most obvious name when I was looking for number games and sudoku etc. *smile*

I came up with the idea of Sudoku 10 in early 2007 but it seems SudoCue was ahead of me publishing the first ClueLess Explosion on the 15th of July 2006.

Now I know my competition! :-)

About two years ago I came up with the idea of combining 10 different sudoku puzzles into one gigantic game where the individual puzzles were all dependent on each other. 810 digits with a designated position in a table with 729 cells! :-) The game board I did design protect at the Swedish Patent and Registration Office. But then... Not much happened... A few games were sold here, and a few games were sold there. But I didn't make much with it. Mainly this was because I didn't have the time to market it, or at least that was what I convinced myself of.. This despite those getting to test the game having loved it.

I guess I imagined there being too much work getting it public. :-)



Now however, this new kind of sudoku game*, which I simply called "Sudoku 10", is available globally on sale through Amazon.com! The book contains 36 sudoku 10 games, that is 360 sudoku games combined in groups of 10!



This is one project that I have finally stopped procrastinating!
