Sea Battle is another of those classics that, with a good opponent (or, even any opponent :-) is just a ton of fun to play. It's got lots of great opportunities for strategy and dastardly trickery. I love that ting-gong SONAR sound effect.

A total of ten Sea Battle box variants have been documented.
