I agree with dreamer234 - I can't get it to work with (9) there, but can get a consistent grid with (10). (8) or less would invalidate some of my early deductions, but might also lead to unique answers.

Can confirm that the top right Area 51 is definitely unsolvable, though I haven't checked for alternate clues.

Well, shoot. I totally treated that 1 in the top corner like it wasn't there. Let me see what I can do to fix this.

OK, replace both of the 9 corral clues with 10 corral clues and it's solvable. Gotta keep the partial-symmetry there. I am about to post an updated sheet.

I may be out of practice with the Area 51 puzzles, but I've tried the top right puzzle four times and keep having trouble with the corral 9 in the upper left. Could you take a look and see if all is correct? I was able to solve the other two puzzles.
