Welcome, and we hope you find our Murder Mystery Machine Guide to All Achievements.


A+ guides for cases 6-8 are not available. So I decided to create one. There have been guides by other users on hidden objects, and how to get an “A+” on the first five.

It isn’t clear how this game determines a A+, but I do know what I have found.

  • Use a hint, or make an incorrect assumption (IE, submit a wrong answer to How Why, Whom, What, Where and When) and you will instantly lose your score to B or C with repeated mistakes. There is no penalty for randomly guessing without deductions.
  • Your score is determined according to how much evidence (objects present on the scene or results from dialogue), how often you make deductions, and how many supporting statements you’ve made. Technically, not all evidence is required. But you only need to do the most important. I received an A+ grade for 2-1 and was absent a piece of evidence. However, I received another A+ for 8-1 while missing the other piece of evidence.
  • According to the patch notes, the scoring system was made more accommodating at some point. If I could guess what changed, the substantiations would have been less relevant to final scoring. Although I will mention some substantiations here, they are not useful in the final score.
  • A case can only get an A+ if it has all the scenes. You can always replay any mistakes you make in a case. I had a bizarre situation where I got an “A+” on Case 7 with no achievement firing. However, the achievement fired immediately after I redid it.
