I _think_ the code I added for the extra large cages works correctly, i.e. the solution is unique.

But if you find a 2nd solution (or more ), do let me know..

Ok, puzzler nicow has provided me with 6 (!) solutions for the puzzle

I'll modify it so it does have a unique solution

(the 1134x cage will be split into a 42x cage (top 2 cells) and a 27x cage (bottom 2 cells)

and will check what went wrong with the solver code


edit: the PDF has been updated.

I didn't answer enough quickly. I found 6 solutions me too. But The problem is solved, now.

Does that mean you were able to submit 6 different solutions? Or were you kicked out on the grounds that you had already submitted a solution?

No, because I thought the puzzle had a single solution, only one of the 6 was accepted as correct.

(and that one is now an actually unique solution)

Apparently I made a very lucky guess, then
