Hi

I'm stuck with this...

Can you tell me the next number with a logical explanation, please?

Thanks a lot

Your pencil marks should show that cells I23 are occupied by a pair. Now consider where the next value of 4 can be placed.

1) Look at box 7 (south-west). Digits 5 and 9 can only go to cells I2 and I3 (hidden pair), which leaves no room for other digits in those cells.

2) Look at column 2. Digit 4 seems to have two possible rows (B and I), but because of the hidden pair it can't go to row I.

3) Thus B2=4 (hidden single); singles to the end.

(Oh, Mike already answered.)
Code: Select all

            *    |    |   |-=( )=-|   |    |      *

Thanks guys :)

I really appreciate your advice. Now looks easy :) (and obvious) but I didn't see the next number about 2 days :oops:

Cheers
