To get clues, keep playing normally! You will get Envelopes with Clues from events, the Mystery Pass, completing areas, and they can also be purchased from the Shop and found in offers. Duplicate Clues can be traded in for rewards in the Evidence Room.

For each duplicate Clue, you'll receive Stars which can be exchanged for Evidence Packs in the Evidence Room. Evidence Packs contain a Clue Envelope and additional rewards. To access the Evidence Room, tap the Evidence Room icon in the bottom right corner of the Evidence Board.

Different types of Envelopes can contain a varying amount of Clues of different rarities. Press the info (i) button on any Envelope to see the amount of Clues and rarities that may be inside.
