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?
Often times the lowest bot plays very well and then randomly hangs their queen in the most obvious way. So the strength greatly varies on whether the bot hangs their queen earlier or later. In general they are not very fun to play against. Getting obliterated and then winning because the bot is programmed to let you win is more frustrating than losing imo.
