and the hard one ER=8.9

Eioru, I think you misunderstand the rules of this game.

Whoever is IT posts a new pattern solvable with singles only. Then others post progressively more difficult puzzles (as measured by Sudoku Explainer) for the same pattern. Whoever posts the most difficult puzzle becomes the new IT.

[Eioru]

Then, can I only keep the first one?

I think you should edit your post (withdrawing both puzzles) and then repost only the first after you win a challenge ... meaning you've become "IT."

Since i neither have a good idea nor much time, this time i want to abandon my right to start the new challenge.

Thanks ravel and congratulations for your puzzle.
It was what I call an easy pattern.

Then, can I only keep the first one?

I think Eioru wants to be the new IT
btw, ronk what does "IT" stand for ?

Although the analogy is not the best, I meant "it" as in children's games of 'hide-and-seek' or 'Simon says.'
