There has never in its entire history been even one puzzle on PuzzleMix with multiple answers, and just like all of the rest this one has a unique, single solution which can be found entirely via reasonable deductive logic.

You probably didn't notice the two bright pink diagonals in the background - this is a Killer X, which means values need to be unique on the two main diagonals too. Because people used to complain when the puzzle didn't "need" the X to solve it, I make an effort to ensure the X puzzles aren't unique until the X is used.

Sorry Gareth, my mistake. For once I missed the diagonals. Stupid boy. No wonder it took me so long just to be a smartarse!. I'll do it again following ALL the rules!

Regards,

Grizz

This is not a valid puzzle. There are multiple solutions but the system only accepts one of them. This is the first time I've seen this on PuzzleMix.

Only one solution. The X is necessary. Without (at least one of) the diagonal clues, I believe there would be four solutions. So the X has to be used. Good puzzle! Thanks, Gareth.

Didn't really get stuck. Little bit tricky to get going, otherwise easy.
