The November 5, 2026 puzzle ran from a server rack at 2 m to Mars at 6,779 km — 6 orders of magnitude apart, drawing on technology, landmarks, dinosaurs, vehicles, space. The pair furthest apart was round 5: Mars is 1.7× as big as Australia.
Answer: Server Rack — 2 m. A server rack measures 2 m (height), which is 1.1× as big as the reference, a refrigerator at 1.8 m.
A full rack is commonly around two metres tall.
Common miss: players tend to compress a server rack when it sits beside a refrigerator — big things get squeezed, small familiar things get stretched.
Answer: Gateway Arch — 192 m. The Gateway Arch measures 192 m (height), which is 1.1× as big as the reference, the Washington Monument at 169.3 m.
St Louis’s Gateway Arch is as wide as it is tall.
Common miss: players tend to compress the Gateway Arch when it sits beside the Washington Monument — big things get squeezed, small familiar things get stretched.
Answer: Stegosaurus — 9 m. A Stegosaurus measures 9 m (length / span), which is about 1.4× smaller than the reference, a Tyrannosaurus rex at 12.3 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 Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
Answer: Family Sedan — 4.6 m. A family sedan measures 4.6 m (length / span), which is about 1.3× smaller than the reference, an American pickup truck at 5.9 m.
The reference almost everyone has parked: a mid-size sedan runs about 4.6 m bumper to bumper.
Common miss: players tend to inflate a family sedan when it sits beside an American pickup truck — big things get squeezed, small familiar things get stretched.
Answer: Mars — 6,779 km. Mars measures 6,779 km (length / span), which is 1.7× as big as the reference, Australia at 4,000 km.
Mars is a little over half Earth’s diameter.
Common miss: players tend to compress Mars when it sits beside Australia — big things get squeezed, small familiar things get stretched.
