bonanova Posted October 9, 2013 Report Share Posted October 9, 2013 This is the hardest I've found. I have not solved it. It may not be clear that cell (9,4) is given as 4. The puzzle turns on whether 84x is 7-2-6 or 7-3-4, and I've run into dead ends both ways. Quote Link to comment Share on other sites More sharing options...
0 DeGe Posted October 11, 2013 Report Share Posted October 11, 2013 (edited) Don't worry about the combinations for 84x or 840x. Just note that the positions of 7 are pretty much fixed for rows 2/3/4. After doing some preliminary entries that are straight forward, eliminate 2+8 as choice for 10+ in row 1; Then eliminate choices for 6789 simultaneously in columns 5 and 6; You will notice that only one possible combination of 6789 in last 2 rows of column 6 gives you possible solution; with any other combination there are conflicts elsewhere. Then the grid opens up and you have an easy solution. Edited October 11, 2013 by DeGe Quote Link to comment Share on other sites More sharing options...
0 bonanova Posted October 11, 2013 Author Report Share Posted October 11, 2013 Nice. I actually stayed up last night and got it. I got the 7s in rows 234 ok. I attacked row 1 by trying stuff for cells 7 and 8. Once I made the right guess and CORRECTLY looking at the consequences, the 1289 cells opened up as you said.
