After completing a scene, you’ll find that the next scene is locked up tight. We’ve got just the thing to unlock it: Hidden Keys!

You can find Hidden Keys by playing Hidden Object Scenes in regular chapters. You may gain any number of Hidden Keys as a reward at the end of a round.

There’s a maximum amount of Hidden Keys that you can hold at a time, and you won’t be able to earn any more if you’re at the limit. So, use them to unlock that next Secret scene as soon as possible!

If you’re a little light on Hidden Keys, you can spend Diamonds to make up the difference. The more Hidden Keys you have, the fewer Diamonds you’ll need to spend. Unlocking a scene this way will consume all the Hidden Keys you currently hold.
