Questions

When you first start That's Not My Neighbor, don't try to rush – check every small detail like the birth date, signature, face, and reactions of your "neighbor," because doppelgangers often reveal their mistakes in very subtle places. Memorizing the real residents' information each day will help you spot the imposter faster, and always stay calm under time pressure, because a hasty decision could cost the entire building.

My personal tip that I find most effective is to play slowly in the first few turns to learn the game's pattern, then gradually increase the speed – like practicing reflexes in rhythm games. Once your eyes get used to the details, you'll spot errors almost instinctively.
