Try to dominate the whole group of islands in this online strategy game! Send ships to surrounding islands and watch out that your ships aren't be drawn into a vortex. So sometimes you'll have to navigate by a roundabout route, via another island!
Drag the mouse cursor from your island to the island you want to conquer. When you release the left mouse button a ship will navigate to that island to conquer it. You can also send more ships at once by first hovering over the other island a ship can set off from and then over the island you want to conquer. Want to cancel an attack? Then press Ctrl and the last selected island will disappear.
