The October 7, 2026 puzzle ran from Hawaiʻi Island at 150 km to the contiguous United States at 4,500 km — about 30× apart, drawing on geography. The pair furthest apart was round 2: Hawaiʻi Island is about 6.7× smaller than metropolitan France.

ROUND 1

How long is Great Britain compared with California?

About the straight-line distance from Land’s End to John o’ Groats.

Common miss: players tend to inflate Great Britain when it sits beside California — big things get squeezed, small familiar things get stretched.
