League point

The oceans of Puzzle Pirates are laid out in an offset grid, but there are no vertical connections. e.g:

Each point in the grid is a possible league point. Some league points have an associated island. Travel between islands must go through adjacent league points. A chart will show the sequence of league points between two islands.

League points can also be memorized, at which point they change from grey to brown on Yer known world. When a blockade is in effect, the ocean view of the island's league will turn red.

League points have several possible colors on the grid; however, the two most common colors will be grey and brown. Memorized league points take precedence over league points in charts. This means that if a league point is memorized, it will appear brown regardless of whether the pirate has the map in hand, or is on a ship with the map on a table.
 * Grey indicates a league point that is available from a chart, either held in the pirate's inventory or on the ship's chart table.
 * Brown indicates a memorized league point.

There are also league points which are temporary in nature, and thus can not be memorized. Usually, these league points are unique to maps for Sea Monster Hunts. These special league points show up as some color other than grey or brown, such as red (for Atlantis) or purple (for Cursed Isles).

League points are shaded (i.e. filled in) to indicate difficulty. The darker the area inside the circle is, the more difficult the area is.

Number of league points per ocean
These tables assist in working out how many league points must be memorized to hold certain portrait items. Extinct points memmed count towards the required percentage for items.
