Defeating the Ancient One and preventing him from awakening is the order of the game in the Eldritch Horror game to prevent the doom of humanity.
Games of all sorts, including board games, have a set way that players need to play them in order for the game to run smoothly, be fair for all players, and end up with a winner or winners at the end. Without rules, players would not know how the game actually works.
The Eldritch Horror board game has its own set of rules for players to use throughout the game. In the game, players take on the roles of investigators and are all on the same team. Specific rules apply for the game to be played successfully.
Eldritch Horror board game
The Eldritch Horror board game is a cooperative game centred around investigation and horror. Players, who assume the roles of investigators, need to solve mysteries, defend humanity from scary horrors, and ultimately, exile the Ancient One from their world.
The Ancient One is an inconceivable power that predates time and is awakening. In the game, the investigators need to prevent the Ancient One from awakening, as all of humanity would be doomed if this were to happen. All team players win or lose together as a unit.
Eldritch Horror board game rules
Eldritch Horror is to be played by one to eight players on one team. The game is played over a series of game rounds that consist of three phases each: the Action Phase, Encounter Phase, and Mythos Phase.
At the end of every Mythos Phase, the Lead Investigator can give the Lead Investigator token to any player of their choice.
In the Action Phase, each investigator resolves up to two actions. This is the main way to move around the board and get beneficial cards and tokens.
During this phase, investigators may perform either a travel action, rest action, trade action, prepare for travel action, acquire assets action, or a component action. Each action can only be performed once during a round.
In the Encounter Phase of the game, each investigator resolves one encounter which often involves reading a short narrative on an encounter card which can have positive or negative effects on the game.
During this phase, if an investigator is on a space that contains one or more monsters, they must resolve a single Combat Encounter against each monster on that space. If there are no monsters, they must resolve a Location Encounter or Token Encounter of their choice.
In the Mythos Phase, the Lead Investigator draws the top card in the Mythos deck and resolves seven possible effects in the order they appear on the card from left to right.
When an effect spawns a gate, a monster is spawned on the same space and when a monster is spawned, players can look at the back of the monster token to resolve its effect immediately after spawning it.
Some additional rules
Many effects require that investigators resolve a test. The investigator will roll a die to determine if they pass or fail a test. Passing a test has benefits, and failing has negative effects.
The investigator will roll a number of dice equivalent to his value in the listed skill. If he rolls at least one success, which could be a “5” or “6”, he passes the test, and if he does not, he fails. The number of successes rolled is called the Test Result.
Various factors can delay investigators and when an investigator is delayed, they need to tip their investigator token on its side to remember that they are delayed.
Losing the game
The game is lost if the Doom token reaches the “0” space of the Doom track and the Ancient One awakens.
If all the investigators have been eliminated from the game, it is lost; if a card effect causes investigators to lose the game, which can frequently happen on Rumour Mythos cards; and if investigators are required to draw a Mythos card but cannot do so because the Mythos deck is empty, the game is lost.
The game is won if the investigators solve all three of the Ancient One’s mysteries.
What happens when the Ancient One awakens?
If the Doom token reaches “0”, the Ancient One will awaken. After it has woken up, when an investigator has been defeated or devoured, the player controlling that investigation is eliminated, and eliminated players do not select a new investigator to lead the investigation, as they are done in the game.
When the Ancient One awakens, it becomes more difficult for investigators to win the game. Every Ancient One sheet will describe one Final Mystery that investigators have to solve in an attempt to win. The sheet usually involves confronting the Ancient One head-on.
