The game is for exactly two players using either the black or white dials to then pulling the Pacific islands in their own sphere of influence. The game is played over three rounds and who has received the most points at the end wins.
Should a player who lost the first two rounds, he can win the game in the third theoretically still. Then he must simply three islands more owned and more sticks on the plan have than your opponent, which is certainly difficult, but not impossible. ;)
Capturing a single island can have an impact on others. So you can put a real chain reaction, when you play just clever enough. The rules are easy to understand and at the latest after the second round has the understood.
