One Night Ultimate Alien supports 4–10 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 One Night Ultimate Alien is 10 minutes. This is the publisher’s estimate for a full game.

The catalogue lists One Night Ultimate Alien for ages 8 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.
