Unlock Short Adventures are 30 to 45 minute Unlocks in a small format, ideal for pocketing or giving as a gift. Unlock! is a cooperative card game inspired by escape rooms. Unlock! brings these experiences into your home, around a table. After familiarizing yourself with the context of the scenario, you begin your adventure in a room (a location map showing various numbers). Search the room for objects! Beware: some may be hidden! Visual and audio puzzles slow your progress. It's up to you to cooperate with your partners to advance and finish on time.

To play, you need the free Unlock! app, compatible with Android and iOS phones and tablets. It allows you to obtain clues, locate hidden objects and enter the codes you discover. The app makes the game very real. It adds to the atmosphere, with music dedicated to each adventure, audio puzzles, terrible penalties and a fatal countdown.

Unlock! Short Adventures: The Ocean's Heart is a scenario of difficulty 2 out of 3.
