Night of the Grand Octopus is a board game released in 2014 for 3–5 players, 20 minutes per game, and ages 7 and up. It was designed by Frédéric Morard and its main mechanics are Set Collection and Simultaneous Action Selection.
Long ago, the Grand Octopus, one filled with cosmically divine powers, reigned over the entire world — until an unfortunate combination of circumstances imprisoned it at the bottom of the ocean. Idle under miles of water, it fell asleep dreaming of the day when its time would come once again. In Night of the Grand Octopus, you are one of the Elect and have been recruited by the Illuminati to form a cult to glorify the tentacled one. What's more, your dreams have told you that the time has come, the stars have aligned so that you can perform the "Ritual of Appeal" and bring the Grand Octopus to surface once again. To perform the ritual, however, you need the right magical components, components to be found in a famous English university for young wizards and witches — and you're not the only one seeking them. In each round, players secretly place their cultist and monster tokens on locations, then reveal those locations at the same time. If only one cultist group occupies a location, that cult gains strength — but if two or more cults want the same spot, they must negotiate or both lose cult strength. If, on the other hand, a rival monster occupies the location, the cultist is eliminated. Gulp!
Night of the Grand Octopus supports 3–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Night of the Grand Octopus is 20 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Night of the Grand Octopus for ages 7 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Night of the Grand Octopus has a complexity rating of 1.4 out of 5 from BoardGameGeek players, which makes it a light game.
