Subjetively, it makes a HUGE difference whether I play a "normal" game against the computer and select stockfish lvl 1 (yes, I'm a very bad newbie), compared to when I select "offline game" and also select stockfish lvl 1. The latter is far more difficult and hardly makes any mistakes (as far as I can tell anyways). I can never beat the offline bot, and almost always beat the online bot. Is this a known quirk of the app?
Oops, thanks for noticing :) updated the title.
