The October 31, 2026 puzzle ran from a leafcutter ant at 1.3 cm to a concert grand piano at 2.7 m — about 211× apart, drawing on insects & bugs, music, pokémon. The pair furthest apart was round 1: a leafcutter ant is about 1.2× smaller than a honey bee.
ROUND 1
How long is a leafcutter ant compared with a honey bee?
Reveal the answer
Answer: Leafcutter Ant — 1.3 cm. A leafcutter ant measures 1.3 cm (length / span), which is about 1.2× smaller than the reference, a honey bee at 1.5 cm.
Leafcutters routinely carry many times their own body weight.
Common miss: players tend to inflate a leafcutter ant when it sits beside a honey bee — big things get squeezed, small familiar things get stretched.
How long is a concert grand piano compared with an adult horse?
Reveal the answer
Answer: Concert Grand Piano — 2.7 m. A concert grand piano measures 2.7 m (length / span), which is 1.1× as big as the reference, an adult horse at 2.4 m.
A concert grand can be more than 2.7 metres long.
Common miss: players tend to compress a concert grand piano when it sits beside an adult horse — big things get squeezed, small familiar things get stretched.
