Chicken Road 2

Chicken Road 2 is an architectural field guide to 29 arch, vault, and spanning forms, covering structures from ancient corbelled openings to modern geodesic domes. Browse the Voussoir Index to explore all 29 profiles. Arrange the collection in course order, compare forms by clear span, or sort them from the oldest surviving examples onward to see how spanning structures developed over time. Open a Keystone Record for a detailed look at each form. Explore its typical span, earliest surviving example, load-bearing method, materials, and a real place where the structure can be seen. Each record also explains how the form works, where it originated, and when temporary centring can be removed during construction. Mark the forms you have personally seen standing in real stone and build a dated record of your discoveries. Choose your own mason's glyph to sign your collection and add structures you still want to find to the Keystone Set. Centring Rush turns architectural recognition into a timed challenge. A family such as round-headed, pointed, vaulted, or long-span is called and nine forms appear. Tap every matching form before the clock runs out. Clearing a course adds time, while each incorrect choice costs three seconds. Use the challenge to move beyond reading profiles and practice recognizing structural families at a glance. Keep playing to improve your best run as you become more familiar with the different forms. Your personal page brings together your mason's mark, name, visited structures, Keystone Set, dated records, and best Centring Rush performance. Chicken Road 2 saves your personal progress on your device so it is ready when you return. Clear your marks and records whenever you want to start the collection again.
