I found a site that will give random fiendish grids,

after basics there is where i am


9 x 2 x 6 x x 1 3

7 3 1 5 2 x x 6 8

8 x 6 x 1 3 x 2 7

2 8 x x 4 x x 3 9

1 9 x x 3 x x 8 4

3 6 4 x 9 x x 7 5

6 7 8 2 5 x 3 x 1

4 2 x x 8 1 7 5 6

5 1 x x 7 6 8 x 2



so I am seeing three UR's, one in the upper third on the (4,5), one in the middle third on the (7,5), and one in the lower third on the (3,9). if this is true, this is the first time I see 3 UR's at the same time in one grid.

Code:
 *-----------*
 |9.2|.6.|.13|
 |731|52.|.68|
 |8.6|.13|.27|
 |---+---+---|
 |28.|.4.|.39|
 |19.|.3.|.84|
 |364|.9.|.75|
 |---+---+---|
 |678|25.|3.1|
 |42.|.81|756|
 |51.|.76|8.2|
 *-----------*

If I've correctly copied it, this puzzle has 12 solutions. No wonder you'd be seeing UR's. Smile
