RYŪ is a board game released in 2015 for 2–5 players, 45 minutes per game, and ages 14 and up. It was designed by Kim Satô and its main mechanics are Set Collection, Auction / Bidding, and Modular Board.
Game description from the publisher: In a galaxy far far away, there is a planetary system composed of a great big sun and nine minor planets, four of which have been developed as mercantile planets more or less under the control of politicians and guilds. On each of these planets are a merchant guild, a guild of smugglers, a bazaar and the galactic government, and players can take special actions on each of these planets. In RYŪ, a game of negotiation, bluffing and cube-drafting, players each represent one of the other five planets in this star system, with each planet having a different type of humanoid – such as sharks, amazons and meka goblins – and its own unique influences. These planets are open to prospecting, and with the proper financing players will be able to dig the resources they need to build their own RYŪ, a mother ship composed of "Rare Metal", "Memory Stone", and "Amber Magic". Players will need to cooperate with one another to raise the necessary resources, but they must also work for themselves in order to maintain an advantage over other players. Once assembled, the RYŪ comes to life as a living spaceship, and its owner wins the game. Probable update from game box on publisher website: Several centuries ago, a celestial Leviathan cried on Titan, our planet. Its tears flooded our cities and our land. The people of the Dragons did their utmost to save as many of us as they could: Goblins, Shibuke, Reptilians, Sharks, and Amazons. The survivors of this deluge were brought to Dala, the highest mountain range of our celestial body, with its 9 majestic summits. Nine summits that soon became nine islands.
RYŪ supports 2–5 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 RYŪ is 45 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 RYŪ for ages 14 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.
RYŪ has a complexity rating of 1.6 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.
