Re: Only Connect
I like it.
Only there is a mistape in the puzzle - two numbers 45. I think there should be 78 instead one of them.

Re: Diogen IPST. 23-30 September 2011
Riad worries about this very much. He cannot decide what to do with puzzle 10. The first variant is to consider results as final and the second is to give maximum points for the solutions with only one king and 52 cells.PuzzleScot wrote:There were a couple of problems in the optimisers.

Here is a zip-file with four sets (I gave them for 45 minutes each).
These files contain grids only (and puzzle names in Russian). Look them - which are interesting.
