Scoring
Each round is worth up to 200 points (1,000 max per game). Scoring uses a Gaussian decay function:
score = 200 × e−(error / 32)²
This means close guesses are rewarded generously (being off by 10 points still earns ~180 pts) while large errors are penalized steeply. Every guess earns at least 10 points. The decay constant of 32 was chosen to make the game feel fair: no need to be exact, but you do need to be in the right ballpark.
