In 'Unlock!: Mystery Adventures – The Nautilus' Traps', you and your friends are plunged into the depths of the ocean on a survival mission. When a sea monster attacks your submarine, the clock starts ticking: you have just one hour to escape before the oxygen runs out. This cooperative escape room card game challenges the group to solve puzzles, combine clues, and crack codes using a deck of 60 cards. The free Unlock! companion app is essential here — it not only tracks time but also provides hints and validates your solutions. Perfect for fans of immersive storytelling and creative puzzles, the game brings all the excitement of an escape room to your table, with the bonus of a theme inspired by Jules Verne's classic '20,000 Leagues Under the Sea'.
