Kohaku: Sundials Expansion is an expansion for Kōhaku released in 2021 for 2–4 players, 30–45 minutes per game, and ages 10 and up. It was designed by Danny Devine and its main mechanics are Tile Placement, End Game Bonuses, and Closed Drafting.
The Sundials mini-expansion offers two new ways to score your koi ponds. The first is the "Sundials" scoring, which gives each player a sundial with N, S, W, and E directions. The sundial is a feature for your garden and each player is dealt 4 cards to place around it. Each player will score bonus points for correctly positioning koi and/or features in their pond according to the relative direction of their sundial cards. This expansion includes 4 sundials and 13 sundial cards. The second is the "Hidden Objectives" scoring. Each player will be dealt 2 cards and will keep 1 of them. The chosen card is kept secret from other players and will be revealed at the end of the game. Points earned from the hidden card will be added to the score from your pond. This expansion includes 12 cards.
Kohaku: Sundials Expansion supports 2–4 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 Kohaku: Sundials Expansion is 30–45 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 Kohaku: Sundials Expansion 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.
Kohaku: Sundials Expansion has a complexity rating of 1.0 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.
