This is entirely possible and its why things like Punk Buster, etc. exist. For a lot of single player games it&#x27;d be hard to verify that an actual human physically executed the plays vs. a bot.  I&#x27;m ok with accepting a high score from someone that went through that level of effort to falsify replays to get on a leader board.  If a puzzle game is truly interesting that kind of cheating isn&#x27;t necessarily optimal anyway.
