hi delrahim69,

please post the text version of the puzzle
(e.g. dot for empty cell, space between cells)

some obvious cells which you missed --
• the 2 for row 16
• the 10 for column 7
• the 11 for row 4 or box 3
• the 14 for row 12 or column 12 or box 11
• the 15 for row 14 or column 4 or box 13
• r2c7 = 1 ("naked single")

what was the difficulty-rating of the puzzle?

should we expect to need a trio?

(yes i did see a trio, in box 9, {3,4,6}
-- but haven't followed it to anything useful)

I entered it into a solver.
This is the text "export" of what I put in.
