Kohaku is a calm koi-pond-building, tile-laying game. Each turn, players will draft both a Koi and Feature tile from the central pond board to play into their personal koi pond.

Score points by surrounding flowers with koi with matching colors, placing frogs next to koi tiles that have dragonflies, and ensuring that baby koi have a safe place to hide by placing them near rocks.

Butterflies score based on line of sight, so make sure to line them up with like-colored koi. Turtles and statues bring a sense of balance to your pond and score points more easily, but perhaps are not as valuable as some of the other features.

You must carefully plan the placement of your tiles, because once they are in your pond, they are not moved! With no restrictions on the shape of your pond, you can create a unique layout to maximize your koi pond appeal.

When there are no koi tiles left to refill the central pond board, the game ends. Players will add the points scored by each feature in their pond. The player with the majority of points wins.
