Surprising that you did not want to play that, but this is your choice.

What would be interesting if you are prepared to do so would be that you comment in the appropriate thread (strategy) on the way you followed to extract them.

I did not open that game, so I have no idea on what I could have found applying my own strategy.

Perhaps some of them were known before the game began.

ronk is right, all of the puzzles I posted, where known to me before the game begun. The strategy here to find more puzzles only applies to this particular pattern (probably there are others): in the pattern

if you delete any clue and add one clue at r5c5, you obtain a puzzle with the same pattern, that is the general idea I used to generate lots of hard puzzles, I did not mind about puzzles with ER<9, but I assume the vast majority of the puzzles in this pattern, are trumpable.

Hi Mauricio,

I think I got your point. When I have no constraint, I work preferably on the canonical form of a puzzle, which in that case leads to the same if i am right.
To be applied in blind mode to the game, it requests more care and a tool I don't have yet to morph back the puzzle. (I am working on priority on a serate clone for the time being).



Thanks again
