How hard are the daily puzzles?

They vary day to day between straightforward arithmetic and trickier logic puzzles, so difficulty isn't constant, some days are quick, others take real thought.

Can I retry if I get it wrong?

Yes, you can try again the same day, there's no limit on attempts, only one puzzle is available per calendar day.

Is scratch paper allowed?

Of course, it's an untimed puzzle meant to be worked through, not a speed test, so take whatever approach helps you solve it.
