Dots only

Postby CarolineMary » Wed Sep 14, 2005 1:44 pm

Some of us use dots to assist in Sudoku solution.

I will pencil in a dot in the appropriate place to indicate that a cell cannot be a specific number.

So for example a cell that contains the layout below could be a 5 or 9.


(Sorry, I know that's probably teaching granny to suck eggs, but I thought it best to explain fully.)

My question is this. Would it be possible to produce a solveable grid that has no actual starting numbers, merely dots indicating two numbers could go in the relevant cells?

(Edit: It lookes like leading spaces go missing, so I replaced with an underscore)

use {code} ..picture in ascii-art.. {code}
with [] instead of {} as here:

Code: Select all

yes, I think it can probably be done but I'm too lazy to figure out an actual example. Maybe later. Or maybe Tso knows this
sort of puzzle already...

edit: it doesn't look good with points, so I try it with "*" :

Code: Select all

* * *

See this post:

The puzzle DIGIT PLACE can be considered an example of exactly what you suggest.

Code: Select all
