An unofficial physical adaptation of the video game Blue Prince by Dogubomb. Draft rooms, manage steps, find Room 46.
Blue Prince is a video game about a house that rearranges itself every day. This is an attempt to put that house on a table.
The board game is a non-commercial fan adaptation — designed to stay faithful to the source material while translating digital mechanics into physical form. Every design decision is documented in the dev log.
The project is in active development. Rules, components, and playtesting are ongoing. All materials are free to download and print.
