This expansion set adds all material needed to play the game with up to 8 players (instead of the standard 4). The set adds four new colors (white, orange, pink and light-blue) and can also be used as a stand-alone 4 player game. The stand-alone game has the same rules as the base game and requires players to reach different islands with their ships by rolling dice. When a player has a ship on an island, if he has a three-of-a-kind matching that island number, the ship grabs one treasure, then returns to port. If a player can't advance a ship, he can place his first mate (1) as a scout on an island to grant himself that power on his next turn, (2) as a thief on a treasure owned by a player with more treasure than him, giving him a chance to steal it next turn if he rolls any three-of-a-kind, or (3) as a defender to remove a thief on one of his treasures. The game ends the round that a player collects his third treasure. If he's the only one with three treasures, he wins; if multiple players have three, then the tied player who has more ships farther from his ports wins.
