Fair use

Your progress

Progress is browser-local; clearing browser storage or changing devices may remove it. Export it from Stats if you want a copy. The experimental lab is unscored and daily puzzle rules may evolve with published updates.

Educational use

The site is a supplementary game, not a certified assessment or a substitute for teachers or a formal curriculum. It is not affiliated with Desmos or Amplify. No independent learning-outcome evaluation is claimed.

Accuracy

Formula entry, simulated physics and visual graphing have limits; experimental equations may be approximate or unscored. Please verify calculations independently when accuracy matters.
