My program claims that all the clues in this puzzle, with the exception of r1c6, r2c3 and r8c1, are individually redundant. Here is a minimal version, with eight clues removed:
Code: Select all
 . . . . . 6 . . .
 . . 3 . . . . . .
 . . . . . . . . .
 . . . . . . . . 6
 . . . . . . . . .
 . . . . 4 9 . . .
 . . . . . . 7 . .
 3 . . . 9 . . 5 .
 . 4 . . 8 . . 2 .


Regards,

Mike

P.S. It would be very helpful if you could post a plain text version of these puzzles for ease of copying.

Yes, now it's minimal. But I doubt if it's still human solvable with an ER of 10.0.

SukakuExplainer 1.17.7 claims it's only 8.2!

My versions of Explainers use SE 1.2.1 solving techniques, ER ratings are slightly higher!
