There is more than 1 answer. Need hint on top left corner.

Jeanvic, I agree - I have found a solution but it has been rejected. Top left corner has me stumped!

Eventually! First columns (only) "1" is 2nd row and first rows (first) "1" is in the 2nd column... Hope it helps.

Thanks, Pearce! Your hint def helped. Even with the hint, there were still multiple solutions but finally found one that worked.

More Hints: [1, (2,4,12)], [2, (1,3,10,13)], [3, (2,6,9-11,13-15)]
(18,4), [(19,20), (3,5)], [{21,22},{2,4}].

Thx for help. Cute picture but would be nice if you made it solvable before posting.

Horrible picture, horrible lack of logic.

The image is really cute. Too bad there are multiple possible solutions. Thank you for the hints.

Thank you for all the tips!
