Was this possible to solve without using the 30?

I got to here without using the 30. I don't think there's any way to get any further without using the 30!

But you can immediately eliminate the 1 from the 30 cage, because that would leave 29, which must be 5-7-8-9, which isn't possible.

I did it without using the 30 until the very end but it took a long time

I think a "Zero puzzle" should usually have exactly the right amount of clues to be solvable. If there was a redundancy, the clue could be deleted. In other puzzles there usually is not an option to leave out clues.

More specifically, exactly the right number of clues to solve at the intended difficulty level. There may be some clues you could remove if you would do a brute-force solve of guess-and-test, but that wouldn't be much fun. For what I consider "reasonable logic", however, you should need to use all the given cages at least once.

Thank you everyone. I somehow thought that for 'zero' puzzles all clues would be needed but I was trying to avoid using 30 since it required the most thought!

Key

• A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
• Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
• If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
• Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
