General Tips

Welcome to the Mystery P.I. - The London Caper walkthrough on Gamezebo. Mystery P.I. - The London Caper is a hidden object game created by SpinTop Games. This walkthrough includes tips and tricks, helpful hints, and a strategy guide to how to complete Mystery P.I. - The London Caper.

A note regarding this walkthrough:

This is a game that relies almost entirely on randomized objects. As a result, no two gaming experiences will be the same. Therefore, the guide, instead of being divided according to “levels”, will be divided into four sections:

General Tips; Crowns, Keys, & Handcuffs; Level End Mini-games, and The Final Puzzle

  • For the sake of the guide, Crowns will be circled in yellow, Keys will be circled in blue, and Handcuffs will be circled in green. Collect all 25 Keys and Crowns to unlock bonus gameplay modes. Collect all 25 Handcuffs to receive an additional +1 million score boost.
  • Objects listed in 'quotes' often require a specific action. I.e. 'cut the butter': use a knife on the butter stick, etc.
  • Objects often have more than one meaning, i.e. bat could refer to the animal or the baseball tool. It could even refer to a word in the picture 'BAT'.
  • There are two modes available: Timed and Relaxed. This can be altered at any time from the Options menu.
  • Hints are available at the cost of a minor score deduction, and will recharge. For unlimited hints, check the Options menu.

The scoring system for Mystery P.I. - The London Caper functions as follows:

  • Finding a Hidden Object: +5,000
  • Back-to-Back Matches: +2,500 (+ multiplier. Note multiplier does not work in relaxed mode)
