The October 12, 2026 puzzle ran from a smartphone at 14.7 cm to a road bicycle at 1.8 m — about 12× apart, drawing on music, insects & bugs, technology, food & drink, vehicles. The pair furthest apart was round 2: a giant centipede is about 1.5× smaller than a computer keyboard.
Answer: Trombone — 90 cm. A trombone measures 90 cm (length / span), which is almost exactly the same size as the reference, a golden retriever at 94 cm.
Measured closed — running the slide out to seventh position adds more than half a metre.
How people guessed: across 16 runs the typical guess was 1.4 m — 58% too large. The most common miss is picturing a trombone far bigger than a golden retriever really allows.
Answer: Giant Centipede — 30 cm. A giant centipede measures 30 cm (length / span), which is about 1.5× smaller than the reference, a computer keyboard at 44 cm.
Scolopendra gigantea hunts bats in mid-air, plucking them from cave ceilings.
How people guessed: across 16 runs the typical guess was 29 cm — almost exactly right.
Answer: Smartphone — 14.7 cm. A smartphone measures 14.7 cm (height), which is about 1.2× smaller than the reference, an ice cream cone at 17 cm.
Phones stopped growing at roughly the limit of what a thumb can reach one-handed.
How people guessed: across 16 runs the typical guess was 15.5 cm — almost exactly right.
Answer: Wine Bottle — 30 cm. A wine bottle measures 30 cm (height), which is about 1.3× smaller than the reference, a PlayStation 5 at 39 cm.
Almost every 750 ml bottle is the same height, whatever the shape of its shoulders.
How people guessed: across 16 runs the typical guess was 41.2 cm — 37% too large. The most common miss is picturing a wine bottle far bigger than a PlayStation 5 really allows.
Answer: Road Bicycle — 1.8 m. A road bicycle measures 1.8 m (length / span), which is about 1.1× smaller than the reference, a Velociraptor at 2 m.
A road bike’s wheelbase is barely a metre; the wheels themselves add the rest.
How people guessed: across 16 runs the typical guess was 1.3 m — 23% too small.
