Weightle — The Daily Physical Balance & Fermi Estimation Game
Weightle is a free daily browser estimation game inspired by Fermi questions, order-of-magnitude physics puzzles, and games like Magnitudle.
How It Works
Every day at 00:00 UTC, a new global balance puzzle is generated. Players estimate how many units of a counter-item (e.g. coffee mugs, playing cards, smartphones) are required to balance a target object (e.g. a refrigerator, a grizzly bear, or a pickup truck) on an authentic two-pan mechanical scale.
- Daily 3: Three progressive rounds (Everyday Baseline, Cross-Domain Mass, and Extreme Macro Disparity).
- Logarithmic Scoring: Evaluates orders of magnitude with fair scoring even for multi-ton estimates.
- Endless Mode: Infinite randomized pairings to test your physical mass intuition anytime.
