Secret of the Mimic is generally reported to be around 8–10 hours for a typical playthrough of the main story, with some players finishing a bit faster or slower depending on how thoroughly they explore.

Quick Scoop

From public forum posts and community chatter, you see a spread like this:

  • Some players: about 7 hours to clear the main storyline at a normal pace.
  • Common estimate: roughly 8–10 hours for a standard run, which is what many people now quote as the expected length.
  • Longer sessions: players who chase secrets and collectibles can push closer to 15–20 hours total, combining first run plus cleanup time.

So if you’re planning a first session, assume one solid weekend’s worth of play (two or three evenings) for the main story, and more if you’re a completionist who likes hunting every secret.
