The October 15, 2026 puzzle ran from a bowling ball at 21.8 cm to an Olympic swimming pool at 50 m — about 229× apart, drawing on sports. The pair furthest apart was round 5: a basketball hoop is 1.5× as big as a surfboard.
ROUND 1
How long is an Olympic swimming pool compared with a Boeing 747?
Answer: Olympic Swimming Pool — 50 m. An Olympic swimming pool measures 50 m (length / span), which is about 1.4× smaller than the reference, a Boeing 747 at 70.7 m.
