Plot.

Gameplay.
Trap.
Sir Charles is staying in Room 3, and the normal assumption is to start the investigation in Room 1- however, pitfalls exist in Room 1 and Room 14. Falling through one of these holes results in death and an instant game over. There is also a trap in Room 16, in which a knife flies through the air towards Sir Charles immediately after he enters. Unless the knife is dodged it hits Sir Charles in the head and kills him, resulting in another instant game over. While solving the case reveals the true criminal, the identity of the person that set these traps remains a mystery. Since Watson does not fall through the pitfall traps, some players suspect that he might have been the one to set them.
Re-interviewing characters.
Each suspect can only be spoken to once per piece of new information— consequently, if there is a piece of information missed the first time around, since it is impossible to talk to them again this can lead to the player becoming impossibly stuck in the game and unable to progress any further. While this bears a sense of reality, it has angered many players.
Bad ending.
There is also a bad ending in the game. During the final stage of the game, the player must present evidence to reveal and prosecute the true criminal. However, if insufficient evidence has been examined/obtained the player will simply receive a game over due to lack of evidence.
Reception.
"Compute!" called "Murder on the Mississippi" "a rich, enjoyable adventure game".
