2 gattai-x (diagonals)

This Sohei-X turned up during testing of my gattai-maker, interesting when I noticed the 8 central boxes were all empty!

Sohei-X (Diagonals) [MEDIUM]
Code: Select all
...8.7..3...3...2.1..2.....4....18...1.....6.....7.4.2...........................
9....7....7..2.......9.8...4..5..........9...617...................4......41.....
.....31......1...................681...1..........7..4...5.9.......8..6....4....5
...........................3.5.4.....9.....5...27....9.....1..4.2...4...5..6.2...

One of the few other gattai-x generated was this Harakiri, the X constraints reduced the number of givens by about a third!
