Bermuda

Off into the deep! From wrecks to riches, when you hunt for treasures in the dark deep in Bermuda, you need to take a long breath. But beware because Neptune's ex-mermaid also lies in wait for a good catch — and it seems many a diver has disappeared from the seabed. Ahoy there!

Bermuda is a cooperative game in which all players dive together. You play against time. And if you are wondering why there is no hourglass in the game - it's because you yourself are the timer! This is how it works:
Once you have taken your unsorted Diving cards in your hands, one of you gives the signal for diving. On "3", all takes a deep breath and simultaneously start to lay out cards. You may keep doing this as long as you - all of you, together - hold your breath. As soon as one of you takes a breath, he falls into the siren's clutches. The round ends immediately.
