League point

The world of Puzzle Pirates is laid out in a offset grid, e.g:

. . . .  . . .  . . ..

Each point in the grid is either an island, a league point, or nothing. League points define the routes that ships can take between the islands, as defined by charts.

League points can also be memorized, at which point they change from blue to brown on the map. When a blockade is in effect, the point for the island under siege will turn red.
