DAILY NO. 1 · VERIFIED MEASUREMENTS
The September 22, 2026 puzzle ran from a giant wētā at 10 cm to Great Britain at 1,000 km — 7 orders of magnitude apart, drawing on technology, dinosaurs, sports, geography, insects & bugs. The pair furthest apart was round 2: a Triceratops is about 1.4× smaller than a Tyrannosaurus rex.
Puzzle #1 asked about a computer keyboard, a Triceratops, an American football field, Great Britain and a giant wētā. 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: Computer Keyboard — 44 cm. A computer keyboard measures 44 cm (length / span), which is 1.3× as big as the reference, a laptop computer at 35 cm.
Full-size boards owe their width to the number pad; tenkeyless models lose about 10 cm.
How people guessed: across 13 runs the typical guess was 57.1 cm — 30% too large. The most common miss is picturing a computer keyboard far bigger than a laptop computer really allows.
Answer: Triceratops — 9 m. A Triceratops measures 9 m (length / span), which is about 1.4× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
The skull alone could reach 2.5 m, among the largest of any land animal.
How people guessed: across 13 runs the typical guess was 18.1 m — 101% too large. The most common miss is picturing a Triceratops far bigger than a Tyrannosaurus rex really allows.
Answer: American Football Field — 109.7 m. An American football field measures 109.7 m (length / span), which is almost exactly the same size as the reference, the Hollywood Sign at 106.7 m.
Goal line to goal line is 100 yards; end zones make the full field 120 yards.
How people guessed: across 13 runs the typical guess was 219.5 m — 100% too large. The most common miss is picturing an American football field far bigger than the Hollywood Sign really allows.
Answer: Great Britain — 1,000 km. Great Britain measures 1,000 km (height), which is about 1.2× smaller than the reference, California at 1,240 km.
About the straight-line distance from Land’s End to John o’ Groats.
How people guessed: across 13 runs the typical guess was 1,896.6 km — 90% too large. The most common miss is picturing Great Britain far bigger than California really allows.
Answer: Giant Wētā — 10 cm. A giant wētā measures 10 cm (length / span), which is almost exactly the same size as the reference, a monarch butterfly at 10 cm.
One of the heaviest insects on Earth — a large female outweighs a sparrow.
How people guessed: across 13 runs the typical guess was 5.6 cm — 44% too small. The most common miss is picturing a giant wētā far smaller than a monarch butterfly really allows.
