It’s less about memorizing degrees and more about training your eye.
WHAT IT FEELS LIKE
Your first estimate is mostly visual intuition; later guesses become a process of narrowing the range from higher-or-lower and closeness feedback.
The first number is a judgment about what you can see, not a measurement from a tool. Afterward, higher-or-lower and closeness clues give you reasons to revise. A wide sweep can look unfamiliar when the diagram is rotated, even though its size has not changed. With only four guesses, deciding how far to adjust after each response matters more than testing every possible angle.
HOW IT WORKS
The highlighted sweep may be rotated, but rotation does not change its size. Four guesses and the warmer-or-colder response help refine a degree estimate rather than requiring a construction tool.
IS THIS FOR YOU?
For players who like visual estimation without vocabulary clues. Entering a number is the only essential input, so the challenge rests on spatial judgment rather than language.
