Editorial interest 77/100 Selection signal · not a rating of the site

A free browser game asks players to resize animals, landmarks, and vehicles against a fixed reference, then score how close their estimates come.

Landing page captured for the 2026-09-28 issue.

For: Players curious about real-world object sizes
Worth noticing: The linked library names examples including a tarsier, dugong, Concorde, Cloud Gate, and Tokyo Skytree.

Field notes

The interface lets players switch between metric and US units and adjust the target with dragging, with arrow-key fine control also described. The site says its object library provides each published object’s named dimension, measurement scope, and source; the extracted page does not include those individual source records.
