They seem to have both hidden constraints(like the 4 digits R34C25 are the same as R25C34).
The first example I needed one trick to solve, the second one at least three.
Can someone find a better way to solve?
After the basics:

Code: Select all

.1.5....5.1.15.......1.5.2.351531.4.

Both are X variants - just different presentations.

Code: Select all

.1......5.1.1..........5.2.3......4. ED=2.9/1.2/1.2
2...6.1......6....5......5...6...4.5 ED=2.9/1.2/1.2


ED=2.9 is my rating for Generalized intersections.
