I can't seem to start this one. The hint says that R2C2 must be 4, but I don't see how the following doesn't work for R12C12: <8> <4> 1 2 x 3 The difference between R1C1 and R1C2 is at least 4, other digits are not between them, the dot constraints are satisfied. What am I not seeing?...

We know at this point that one segment of the line is 2 cell long and can contain 1/5/7/9. We don't know how long the rest of the line is. So the help continues: "Considering the sum of these two as a factor of the total sum of the line only allows for the possibility of th...
