Better than that; it is possible to score 100% accuracy for an entire game. I've done it a few times, but the "easiest way" is to play solid and deep opening theory (all "book" moves) and then agree to a draw. Both sides should score 100% accuracy then.
Here was a "game" that was unrated where @QuickV (a chess.com friend of mine) and I created a 100%-100% game. CAPS 2.0 by chess.com is supposed to make super high accuracy games (like 100%) as well as super low accuracy game much harder to reach though.
A lot of haters have been telling me that 100% accuracy is not possible. I just want to show this to the haters to prove that it IS possible and that I WAS able to do it. No! Don't make excuses. Admit that I am a great player and that my achievements are incredible. End of.
Here is the game:
I was on the white pieces.
Here is the analysis if you do not believe that it is 100%
