DAILY NO. 4 · VERIFIED MEASUREMENTS
The September 25, 2026 puzzle ran from a violin at 59 cm to Japan at 3,000 km — 6 orders of magnitude apart, drawing on landmarks, geography, animals, music, technology. The pair furthest apart was round 4: a violin is 1.5× as big as a PlayStation 5.
Puzzle #4 asked about the Great Pyramid of Giza, Japan, a grizzly bear, a violin and a 55-inch television. 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: Great Pyramid of Giza — 138.5 m. The Great Pyramid of Giza measures 138.5 m (height), which is 1.3× as big as the reference, a Saturn V rocket at 110.6 m.
Erosion has reduced the pyramid to about 138.5 metres today.
How people guessed: across 22 runs the typical guess was 230.6 m — 67% too large. The most common miss is picturing the Great Pyramid of Giza far bigger than a Saturn V rocket really allows.
Answer: Japan — 3,000 km. Japan measures 3,000 km (height), which is 1.1× as big as the reference, Greenland at 2,670 km.
Japan’s island arc extends around 3,000 kilometres.
How people guessed: across 22 runs the typical guess was 3,045.7 km — almost exactly right.
Answer: Grizzly Bear — 2 m. A grizzly bear measures 2 m (length / span), which is almost exactly the same size as the reference, a queen bed at 2 m.
A grizzly can measure about two metres from nose to rump.
How people guessed: across 22 runs the typical guess was 2.5 m — 26% too large. The most common miss is picturing a grizzly bear far bigger than a queen bed really allows.
Answer: Violin — 59 cm. A violin measures 59 cm (height), which is 1.5× as big as the reference, a PlayStation 5 at 39 cm.
A full-size violin is always about this long; smaller fractions exist for children, down to 1/16.
How people guessed: across 22 runs the typical guess was 61.4 cm — almost exactly right.
Answer: 55-Inch Television — 1.2 m. A 55-inch television measures 1.2 m (length / span), which is 1.3× as big as the reference, a golden retriever at 94 cm.
A 55-inch TV is 55 inches corner to corner; across the front it is only about 1.2 m.
How people guessed: across 22 runs the typical guess was 1.2 m — almost exactly right.
