Secret Moon is a board game released in 2014 for 5–8 players, 10 minutes per game, and ages 10 and up. It was designed by Seiji Kanai and its main mechanics are Variable Player Powers, Player Elimination, and Deduction.
Secret Moon is Seiji Kanai's interpretation of a Werewolf-like team deduction game, and a sequel to Love Letter. He is not very fond of stories of killing, thus the more romantic background. Also, he claims to be horrible at chatting and bluffing, so Secret Moon is a game that can be enjoyed by people like him, with less need to bluff and deduction based more on game flow and rules. This was posted on an Italian gaming website (excuse the poor translation, my Italian is very poor): (Edited with help from the English rules.) A game published by Kanai Factory Drawings by Noboru Sugiura Up to three players will be part of "Team Princess" (Princess, Wanderer and Priestess), and the rest are "Team Minister" (Minister and four Guards). The Priestess can pretend to be part of the Minister's team, all in the name of helping the Princess. Team Princess wins if the Minister is captured or the third round ends. Team Minister wins if the Princess is captured or BOTH the Princess and the Wanderer are revealed. At the table you cannot speak except to make or answer questions permitted by the rules. The game lasts three rounds, and each round turn order cards are dealt. On their turn, you may: - Inspect: look at another player's character card. - Inquire: ask another player "who goes there!", and the appropriate response is on their character card. - Accuse: guess another player's character. If correct, they reveal their card. Otherwise, reveal yours. - Hide/protect: defend yourself or another player for the rest of the round. (Cannot be done in third round) - Disrupt: cause another player who hasn't taken their turn yet to lose their turn this round. You are then captured. - Capture: "capture" a revealed character. A captured character is out of the game, but still wins if their team wins. (Guards may not capture) Minimum age: 10 + Language use in the game : Minimal Duration of the game : 10 min Players: 5-8 Manual Language : English - Japanese
Secret Moon supports 5–8 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 Secret Moon is 10 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 Secret Moon for ages 10 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.
Secret Moon has a complexity rating of 1.2 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
