From the heart of Prague’s Old Town rises one of the greatest marvels of medieval engineering — the Orloj, the Astronomical Clock that has marked time for centuries. In this thematic eurogame, players take on the role of master builders, striving to leave their mark on history by constructing the magnificent celestial calendar of the Orloj.

Each turn, you’ll place workers on the clock’s dial to gain resources, perform actions, and advance your mastery in astronomy, mechanics, and art. You can hire assistants, build the apostles’ carillon, and develop your expertise across multiple tracks, earning new abilities as your knowledge grows.

Balance, precision, and cosmic harmony will be the keys to success. When the calendar is finally complete, the player with the most harmony points becomes the legendary architect of Prague’s Orloj!
