Just understand it's completely a relative stat. How many moves are in the game? What was the accuracy of your opponent? A beginner's high accuracy is not comparable to any other higher level.
What accuracy % do you consider a “good” game?
If your opponent doesn't resign you can rack up 20 good moves in a row in an endgame when you push a pawn and chase their king. Also sticking to a b grade plan that you actually understand and gets you a winning advantage is better than playing above your skill level and losing to a line that might be better but is too complicated for your current ability. If you care about winning that is

Anything above 90 is reasonably good, but the games that bring me satisfaction are more often complex blunderfests where my creativity and persistence paid off.
My average accuracy is around 80% and last time I got 0 blunders and 0 misses I don’t know the accuracy of that game I was not showing sometimes it shows me the accuracy sometimes it does not. I am 540elo

Anything above 80 is a game you should be proud of!
60-70% is usually average for lower ratings, its critical that you analyze these games to later improve and start gradually increasing your average accuracy
I just played a 20 move game (I know its short) at 600 elo and i had 94.8 accuracy, and my opponent had 76.5.I feel pretty proud.
is 94,5 good for an 880 in a 17 move game?
that's a GM average but in a match is okay to have that accuracy , if you keep it with that elo, in 9 games your account gonna get banned 100%
( accuracy% vs rating# ) is NOT one of the criteria the Cheat Detection Team uses for detecting cheaters. At most, it might draw their attemtion to a particular account. By itself and uncorroborated, it would NEVER trigger a ban.
Ofc don't but u can't have low ratting having over 90 accuracy in the most of your matches, believe me
