new to Sudoku

Postby jcbarber » Sun Feb 17, 2008 8:59 pm

I'm new to Sudoku and have found that I get lost in the logic at a certain point in the puzzle books I have tried. The books are "Sudoku for Dummies" (I got lost at the tough ones) and "Mensa Guide to Solving Sudoku" (I got lost at the X-wings swordfish etc.). Is this typical? I've worked over 250 puzzlers since Oct 07. I figure I need more practice with puzzles that use the lodic methods I mentioned above. Any ideas or suggestions as how to "unstick" myself

well you could try reading other people's explanations of these techniques, which you'll find here:
or maybe my explanations which are here:

computationally x wings are as hard as pairs, swordfish are as hard as triples and jellyfish are as hard as quads. but for some reason people are wired differently to computers and somehow these fishy patterns (as x wings, swodfish and jellyfish are known) seem harder to most than subsets (as pairs, triples and quads are known). so you're not alone.
