DAILY NO. 2 · VERIFIED MEASUREMENTS
The September 23, 2026 puzzle ran from a Goliath beetle at 11 cm to a high-speed train at 200 m — 3 orders of magnitude apart, drawing on animals, vehicles, insects & bugs, music, dinosaurs. The pair furthest apart was round 1: a grizzly bear is about 1.2× smaller than an adult horse.
Puzzle #2 asked about a grizzly bear, a high-speed train, a Goliath beetle, a concert harp and an Allosaurus. Each answer below gives the measured size, the reference it stood beside and the source behind the number. Want the surprise first? Replay this puzzle — archived days never touch your streak.
Answer: Grizzly Bear — 2 m. A grizzly bear measures 2 m (length / span), which is about 1.2× smaller than the reference, an adult horse at 2.4 m.
A grizzly can measure about two metres from nose to rump.
How people guessed: across 3 runs the typical guess was 3.5 m — 74% too large. The most common miss is picturing a grizzly bear far bigger than an adult horse really allows.
Answer: High-Speed Train — 200 m. A high-speed train measures 200 m (length / span), which is 1.1× as big as the reference, the Roman Colosseum at 189 m.
A complete high-speed trainset can be around 200 metres long.
How people guessed: across 3 runs the typical guess was 20 m — 90% too small. The most common miss is picturing a high-speed train far smaller than the Roman Colosseum really allows.
Answer: Goliath Beetle — 11 cm. A Goliath beetle measures 11 cm (length / span), which is 1.1× as big as the reference, a monarch butterfly at 10 cm.
Among the heaviest insects alive — the larvae can reach 100 g.
How people guessed: across 3 runs the typical guess was 11 cm — almost exactly right.
Answer: Concert Harp — 1.9 m. A concert harp measures 1.9 m (height), which is about 1.1× smaller than the reference, a US interior door at 2 m.
Forty-seven strings holding close to a tonne of combined tension.
How people guessed: across 3 runs the typical guess was 1.8 m — almost exactly right.
Answer: Allosaurus — 8.5 m. An Allosaurus measures 8.5 m (length / span), which is about 1.1× smaller than the reference, a Triceratops at 9 m.
The common large predator of its day: far more Allosaurus fossils exist than T. rex ones.
How people guessed: across 3 runs the typical guess was 10.6 m — 24% too large.
