The October 28, 2026 puzzle ran from an Ankylosaurus at 8 m to a Brachiosaurus at 22 m — about 3× apart, drawing on dinosaurs. The pair furthest apart was round 4: an Ankylosaurus is about 1.5× smaller than a Tyrannosaurus rex.
Answer: Stegosaurus — 9 m. A Stegosaurus measures 9 m (length / span), which is almost exactly the same size as the reference, a Triceratops at 9 m.
A brain the size of a lime, in a body as long as a bus.
Common miss: players tend to inflate a Stegosaurus when it sits beside a Triceratops — big things get squeezed, small familiar things get stretched.
Answer: Triceratops — 9 m. A Triceratops measures 9 m (length / span), which is about 1.2× smaller than the reference, an American school bus at 10.7 m.
The skull alone could reach 2.5 m, among the largest of any land animal.
Common miss: players tend to inflate a Triceratops when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
