Game Boards

Eldritch Horror and its expansions contains 1 main board (World Map) and 3 side boards. While one or two side boards are in play, "game board" refers to both the main board included in Eldritch Horror Core Game and the side boards from the expansions. "Side board" refers to the side board but not the main board.

## Main Board

*Main article: World Map*
The game board supplied with the Core Game and used in every game of Eldritch Horror represents a world map that consists of spaces connected by paths. It is called Game Board in the rules, but to avoid confusion between the game boards, this wiki uses the term World Map. The majority of Ancient Ones do not need any side boad and only use the World Map.

This board also contains the Doom and Omen tracks, as well as the Reserve.

## Side Boards

Three side boards are included in some expansions, they add additional locations connected to the world map and each side board has its specific mechanics, for example the Antarctica side board uses local actions and the Dreamlands side board uses Dream-Quest Encounters.

To use a side board, it is necessary to play against an Ancient One whose setup requires a specific side board, or to play with a Prelude that requires setting up a specific side board. It is therefore possible to play a game with up to two side boards (one set by an Ancient One and another by a Prelude), although this may be unusual, except in campaign mode.

### Antarctica Side Board

*Main article: Antarctica Side Board*

The Antarctica side board was introduced in the  Mountains of Madness Expansion. It consists of 6 additional locations, connected to the main board by a Local path from  Miskatonic Outpost to  Antarctica. The particularity of this board is that all the spaces have no type, but each of them have a specific Local Action or a special effect. All of the spaces are connected to each other by Uncharted paths and all  Clues encountered on this board requires to draw an Antarctica Research Encounter instead of the Ancient One Research Encounter.

This sideboard is only used whenever the  Rise of the Elder Things Ancient One or the Doomsayer from Antarctica Prelude is in play.

### Egypt Side Board

*Main article: Egypt Side Board*

The Egypt side board was introduced in the  Under the Pyramids Expansion. It consists of 6 additional locations, connected to the main board by a Ship path and many Local paths. This board represents more details about a region of the World Map instead of adding a new area outside, which is why it has only few specific rules and is fully integrated into the world, being one of the the most accessible side board. Due to the most of the locations being interconnected by a Local path, it is quite easy to reach these spaces.

This sideboard is only used whenever the  Nephren-Ka Ancient One, the Under the Pyramids Prelude, or the In the Lightless Chamber Prelude is in play.

### Dreamlands Side Board

*Main article: Dreamlands Side Board*

The Dreamlands side board was introduced in the  The Dreamlands Expansion. It consists of 7 additional locations, connected to the main board by Local paths through 3 Dream Portal tokens that are spawned randomly on spaces of the World Map that may contain a Gate. This board also uses a specific Encounter type, the Dream-Quest Encounters that have mechanics similar to Expedition and Mystic Ruins encounters.

This sideboard is only used whenever the  Hypnos Ancient One, the Otherworldly Dreams Prelude, or the Aid of the Elder Gods Prelude is in play.
