the most difficult achievements


i have castle victory
I delivered mate by castling and I don't see that in my achievements. Not even as a blank.

l Got puzzle machine!
(100 puzzles in 2 hours)
But the hardest is puzzle addict. (10000 puzzles correctly solved)

I somehow got full house and nick of time and didn’t notice which games.
to get nick of time, I possibly used a pre-move in bullet or blitz.
getting full house is probably the easier of the two.
edit/ try get a checkmate in under ten moves to get full house.
