Celestial Tiles: Four Seasons

Celestial Tiles: Four Seasons is a deterministic observatory-calibration puzzle. Restore a dormant orrery by placing carved tile faces into rotating rings, seasonal gates, and star bridges. Every tile value controls a visible angle, time step, or alignment state as you connect star arcs, anchor lunar stations, and reopen the observatory one instrument at a time. Explore four seasonal campaigns, eclipse trials, solar-dial timing studies, tidal calendars, comet windows, workshop repairs, a free observatory, and a date-based almanac. Each challenge presents a complete board, explains its constraints on-screen, and lets you inspect every result without random outcomes. Local progress, saved configurations, and alternate calibration notes remain available offline.
