    do not check for 1 solution on any of the grids they publish,

    and rely solely on the honesty of the puzzle maker
    to verify the grid is in fact solvable with unique solution.

say i set a fine puzzle with exactly 1 answer,
i even set it in a PDF -- ready-to-print

but the newspaper prefers their own font,
so they go through manual typesetting
and ruin the puzzle

    they even put my name at the top,
    so you blame me---

I can now confirm that there are three possibilities (already found):
Code: Select all
1...2...3..6...7...54.3.89....6.2...8.9...1.6...8.4....32.7.64...1...5..7...8...9    r5c1 -> 8 
1...2...3..6...7...54.3.89....6.2...4.9...1.2...8.4....32.7.64...1...5..7...8...9    r5c9 -> 2 
1...2...3..6...7...54.3.89....6.2...4.9...1.6...8.4....32.7.68...1...5..7...8...9    r7c8 -> 8 

The more difficult task is to find a minimal puzzle for this pattern!
