Complete sets of this version are now very rare and in good condition can sell for more than £100 (UK pounds - as of 2010).
A major revision in 1958 saw the playing area change to a folding board with a square cut out for a plastic tray insert as Treasure Island.
These cards contain instructions, either bad ("You are blown to Cliff Creek") or good ("Take treasure up to 5 in total value").
The US version of the game was called Trade Winds and used slightly different rules and board additions.
The winning condition was not changed, gathering treasure worth 20 points at the player's home port.
