First 12 Clue Sudoku-X
Posted: Mon Jul 23, 2007 5:49 pm
The minimum number of clues for a Sudoku-X has been 13 for the last two years. This weekend, I started a search for more 13's and possibly a 12.
Here's a 12 I found this morning.

I will start a new page on the main site, where I will explain my search techniques and post a list of additional 12-clue Sudoku-X puzzles I found later today.
