The October 31, 2026 puzzle ran from a Velociraptor at 2 m to a Diplodocus at 25 m — about 13× apart, drawing on dinosaurs. The pair furthest apart was round 2: a Diplodocus is 2× as big as a Tyrannosaurus rex.

ROUND 1

How wide is a Pteranodon wingspan compared with a family sedan?

Reveal the answer

Answer: Pteranodon Wingspan — 6 m. A Pteranodon wingspan measures 6 m (length / span), which is 1.3× as big as the reference, a family sedan at 4.6 m.

Measured across the wings — a span no living bird comes close to.

Common miss: players tend to compress a Pteranodon wingspan when it sits beside a family sedan — big things get squeezed, small familiar things get stretched.

ROUND 2

How long is a Diplodocus compared with a Tyrannosaurus rex?

Reveal the answer

Answer: Diplodocus — 25 m. A Diplodocus measures 25 m (length / span), which is 2× as big as the reference, a Tyrannosaurus rex at 12.3 m.

Almost half of Diplodocus was tail, which may have cracked like a whip.

Common miss: players tend to compress a Diplodocus when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.

ROUND 3

How long is a Brachiosaurus compared with a Spinosaurus?

Reveal the answer

Answer: Brachiosaurus — 22 m. A Brachiosaurus measures 22 m (length / span), which is 1.5× as big as the reference, a Spinosaurus at 15 m.

Brachiosaurus held its neck upward, making it far taller than long-tailed sauropods of similar length.

ROUND 5

How long is a Velociraptor compared with a queen bed?

Reveal the answer

Answer: Velociraptor — 2 m. A Velociraptor measures 2 m (length / span), which is almost exactly the same size as the reference, a queen bed at 2 m.

Real Velociraptors were closer to turkey-sized than movie monsters.

Common miss: players tend to inflate a Velociraptor when it sits beside a queen bed — big things get squeezed, small familiar things get stretched.
