Does everyone get a badge for the weekly Sudoku ?

No, it’s months in between badges.  My last weekly one was awarded on 11/21 and that was for 12 weeks.  The next weekly badge is for 30 weeks, so won’t get that until the end of March.
 
The last individual weekly badge was for 100 puzzles and I got that on 12/2.  The next one is for 200 puzzles, so won’t get that until the middle of March.
 
And the one for no power-ups and no mistakes for the weekly were awarded 11/7. The next ones should be earned the end of January.
 
They are more and they all different, you just have to look at the dates you got yours, and figure out how long it will be until the next one.

Thanks, Moms, I thought it was just me.

You’re very welcome.  You just have to read the requirements for each badge.  I’ve never been cheated out of a badge, always get it when I earn it.
