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.

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."

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

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

Here's my first contribution :
Code: Select all
 1 2 . | . . . | . 3 4
 5 6 . | . . . | . 1 7
 . . . | . . 6 | . . .
-------+-------+-------
 . . 8 | 4 . 9 | . . .
 . . . | . . . | . . .
 . . . | 6 . 5 | 4 . .
-------+-------+-------
 . . . | 1 . . | . . .
 4 9 . | . . . | . 7 1
 2 1 . | . . . | . 8 5    SE=8.3

still an easy pattern...

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

Well, after 2 weeks' absence so much has happened. Here's my rapid response to keep your Pattern Game moving:
Code: Select all
 . . . 1 3 6 . . .
 . . 7 . . . 3 . .
 3 4 . . . . . 1 9
 . . 6 . . . 5 . .
 . . . 7 . 1 . . .
 . . . . 9 . . . .
 . . . . 2 . . . .
 . . . 9 . 8 . . .

This reaches SE 4.4 when only 13 cells remain unsolved:!:
