Fear of Colors

Hello all,

I'm a sudoku newbie. (Playing for less than a week now). I consider myself easily addicted, so in a short time I feel I conquered a lot of solving techniques already.
The one thing that always breaks me is coloring.

I never know where to start coloring, and what to do when a cell has multiple conjugates. Does anyone have a link/site that really explains coloring extensively? Most links I found here seem to use the same explanation, and it just doesn't hit the spot.

Thanks in advance,

Braniac.

Hi Braniac,

Coloring is a way to visualize the binary nature of strong links. When you understand this concept, you are able to apply a whole range of solving techniques that depend on strong links.

A good introduction into strong links is written by Havard. Just follow this link. After absorbing this article, reread the coloring explanations mentioned in the solving technique index.

cheers, Ruud.
