Puzzle Detective is not just a match 3 game, but it also has good gameplay. You match three to find clues. Then you fly from one location to other location closer to the items you found earlier so that you can narrow down your suspect list. With a few clues, you can either guess where the criminal went or use the clues to eliminate suspects.
After you get enough clues, you'll be able to single out the criminal who stole the popular diamond. You'll get higher rank as you arrest more criminals. This game is similar to Diamond Detective.
