# 0hn0: is that this right deduction?

Starting with:

We quickly get to this:

If you have a look at the empty spot within the decrease proper nook, you’ll be able to see that whether it is Blue, then the 6 on the prime of the column can’t see that spot, so there have to be Red between it and the 6. If that is the case this spot will not be seen by any Blue that begins with a quantity.

There isn’t any rule {that a} Blue will at all times be seen by a Blue with a quantity however I’ve by no means seen a scenario like that – it will imply that the spot may be both Blue or Red which might be ambiguous (once more, nothing towards that within the guidelines).

There are different methods to proceed from right here, this isn’t a troublesome puzzle, however I do really feel that I can confidently put Red within the decrease proper empty spot based mostly on the deduction above. Is this a sound deduction? If we clear up the puzzle by traditional means, positive sufficient there will likely be Red there.
