Mr. Jim Bumgardner from KRAZYDAD has given me permission to post his blog on mine ^^
I ran across his marvelous site, back in about 2-3 months ago, when i was googling for some tutorials and techniques on how to solve sudoku :P and his site now has been one of my favourites :)
Mr. Jim has a lot of comprehensive and usefull techiniques about sudoku strategies, you really should check it out ;)
As i browse even deeper on his site, i found that he too, made lotsa puzzles, including jigoku - a brilliant twist to sudoku, kakuro, and mazes ! super duper hard mazes ;) ! Mr. Jim even offers a free printable version of his puzzles ;) and if you liked his puzzles, then a little donation could help ;) well at least for the effort right ;)
So, drop by and enjoy the KRAZYDAD ^^ you'll surely hafta bookmark it ;)
