Sea of Mystery is a 1981 role-playing game adventure for Tunnels & Trolls published by Flying Buffalo.
Sea of Mystery is a solo adventure in which the player character encounters pirates, slave galleys, storms and more on the high seas.
Russ Williams reviewed Sea of Mystery in The Space Gamer No. 49.[1] Williams commented that "The situations are quite varied. I found one or two a bit hard to swallow, and some seemed contrived. However, it is basically a good, solid adventure with a welcome change in format from most other Flying Buffalo solo dungeons. I recommend it."[1]
