Size Master

How big is a desk lamp, really? 🤔

 Size Master is a daily estimation game that trains your feel for scale. Every day you get: 

● 5 rounds of silhouette size-guessing — a reference object and a mystery silhouette are drawn to true scale. Drag the slider (or the silhouette itself) until the sizes feel right, lock in, and see how close you were. The closer you are, the more of the 100 points you keep. 

● 1 number quiz — estimate a single real-world figure (one shot only!). Scoring is merciless but fair: within 6% error = full marks, and the tolerance widens step by step down to zero. Highlights: 

● 120+ hand-picked silhouettes spanning 8 orders of magnitude — from a 7 mm ladybug to the 21,196 km Great Wall 

● A true-scale scene with a 1-2-5 scale bar: no numbers shown until you lock in — pure eyeballing 

● A new deterministic puzzle every day — everyone plays the same set 

● Copy a 🟩🟨🟥 share grid and challenge friends 

● Practice rounds that don't burn your daily attempt 

● 中文版 & English in one build (switch in the top bar) .
