Drag it to your guess. The closer you get, the more you score.
Each day starts with one structure and how far it bends under its load. Then it changes five times. Guess the new deflection each time.
Deflections come from a linear-elastic frame analysis with nominal material stiffness. Self-weight is ignored, and every member stays well below yield and buckling. A new game starts at midnight UTC. Progress stays in this browser.
Same structure and changes as the original day. Your first score is saved; archive play doesn't count toward your daily streak.
The first puzzle is today. Come back tomorrow for the archive.
Same structure, same five changes. Who has the better feel for it?
