I'm new to this addiction and could badly do with some help. Puzzle number 126 (and it's only mild). Have made a little progress but got stuck at:
x49 25x xxx
17x xx4 x9x
x3x xx7 x8x
xx3 xx2 xxx
x84 x7x 23x
xx1 4xx 6xx
x9x 6xx x4x
41x xxx x67
xxx 745 1xx
Any help about where to go next would be much appreciated.
thanks
