Lucky Cards are special collectibles that grant rewards upon collecting a Royal Flush. A Royal Flush is a term when you have 5 cards in deck up from Ten to Ace in the same deck.

Receiving Lucky Cards

After clearing a crime scene, players are given the choice to send a Lucky Card to the teammate they had chosen as their partner for the scene.

You can also receive Lucky Cards when you share a bottle of Orange Juice or a bag of Potato Chips after leveling or ranking up. Indeed, your friends (or any other Criminal Case player who is not in your teammates list) who receive those rewards can thank you by sending you a random Lucky Card. Likewise, when you get the snack from a friend, you can send them a random Lucky Card.

Another way is to have Police Pets find Lucky Cards for you after you have cleared a crime scene. Only certain pets, however, have the ability to find Lucky Cards.
