Players are deep-sea divers trying to collect treasures from a sea floor littered with shipwrecks, and gather seashells to build vibrant aquariums. Draft dice from the tide pool to guide your plans, then dive in to grab the loot you need. The trick is that any diver next to you in the wreck will also be able to grab treasure... this creates awesome tension between getting what you want and trying not to help the wrong rival at the wrong time!
