The heron flies over the Himeji sky while the Daimio, from the top of the castle, watches his servants move. Gardeners tend the pond, where the koi carp live, warriors stand guard on the walls, and courtiers crowd the gates, pining for an audience that brings them closer to the innermost circles of the court. When night falls, the lanterns are lit and the workers return to their clan.

The White Castle is a Euro type game with mechanics of resource management, worker placement and dice placement to carry out actions. During the game, over three rounds, players will send members of their clan to tend the gardens, defend the castle or progress up the social ladder of the nobility. At the end of the match, these will award players victory points in a variety of ways.
