In Scuba, two to four players jump from the diving boat to have a fun time diving. While moving and flipping over the tiles on the board, they hope to find spectacular fish, mammals and corals, make combinations and score big points.
Or just look at fish other players already discovered...
Maybe they will even find treasure! But be careful not to lose your mask or get bitten by an octopus... Make dust so other players can't find any fish that turn. And be wary of currents sweeping all fish around the board.
And even more important, keep an eye on your air at all times! If you plan badly and use all your air while still diving, you won't live to tell your stories...
