Is this Valid?

Postby yalgaar » Wed Dec 28, 2005 3:44 pm

I have 3 cells. The candidates for them are as follows:

Cell 1: 1,2,3
Cell 2: 1,2
Cell 3: 1,3

Is it valid to take out "1" from each cell which would give me the following result:

Cell 3 as "3"
Cell 2 as "2"
Cell 1 as "1"

Is tha above logic valid? If not is there any other way to solve this?

Thanks

I'd say "no and no". You need more info to do anything with that few clues.

Cell 1: 1,2,3
Cell 2: 1,2
Cell 3: 1,3

given these clues you could have:
cell 1: 1
cell 2: 2
cell 3: 3
OR
cell 1: 2
cell 2: 1
cell 3: 3
OR
cell 1: 3
cell 2: 2
cell 3: 1

which of these happens in your puzzle will depend on other squares!

If you have a naked, pair locked candidate etc then it may be appropriate to remove the 1 but not otherwise.

Why not post your grid.

I don't have a grid. I was just trying to develop logics. I come across the mentioned situation many times while solving.

Cell 1: 1,2,3
Cell 2: 1,2
Cell 3: 1,3

As it stands this a naked triple, the numbers 1,2,3 can be removed from any other cells in that row, column or block in which it appears.
