The October 8, 2026 puzzle ran from a Velociraptor at 2 m to an Iguanodon at 10 m — about 5× apart, drawing on dinosaurs. The pair furthest apart was round 5: an Allosaurus is about 1.3× smaller than an American school bus.
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: Iguanodon — 10 m. An Iguanodon measures 10 m (length / span), which is about 1.2× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
Its thumb spike was first reconstructed, wrongly, as a horn on the nose.
Common miss: players tend to inflate an Iguanodon when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Ankylosaurus — 8 m. An Ankylosaurus measures 8 m (length / span), which is about 1.1× smaller than the reference, a Stegosaurus at 9 m.
The tail club weighed tens of kilos and could swing hard enough to break bone.
Common miss: players tend to inflate an Ankylosaurus when it sits beside a Stegosaurus — big things get squeezed, small familiar things get stretched.
Answer: Velociraptor — 2 m. A Velociraptor measures 2 m (length / span), which is about 1.1× smaller than the reference, a three-seat sofa at 2.2 m.
