The October 29, 2026 puzzle ran from a cruising sailboat at 10 m to the RMS Titanic at 269 m — about 27× apart, drawing on vehicles. The pair furthest apart was round 3: a New York subway car is 1.7× as big as an American school bus.
ROUND 1
How long is a high-speed train compared with the Roman Colosseum?
Reveal the answer
Answer: High-Speed Train — 200 m. A high-speed train measures 200 m (length / span), which is 1.1× as big as the reference, the Roman Colosseum at 189 m.
A complete high-speed trainset can be around 200 metres long.
Common miss: players tend to compress a high-speed train when it sits beside the Roman Colosseum — big things get squeezed, small familiar things get stretched.
How long is the RMS Titanic compared with a high-speed train?
Reveal the answer
Answer: RMS Titanic — 269 m. The RMS Titanic measures 269 m (length / span), which is 1.3× as big as the reference, a high-speed train at 200 m.
Titanic was about 269 metres long — shorter than many modern container ships.
Common miss: players tend to compress the RMS Titanic when it sits beside a high-speed train — big things get squeezed, small familiar things get stretched.
How long is a New York subway car compared with an American school bus?
Reveal the answer
Answer: New York Subway Car — 18.3 m. A New York subway car measures 18.3 m (length / span), which is 1.7× as big as the reference, an American school bus at 10.7 m.
A common New York subway car is about 60 feet long.
Common miss: players tend to compress a New York subway car when it sits beside an American school bus — big things get squeezed, small familiar things get stretched.
How long is a cruising sailboat compared with a Tyrannosaurus rex?
Reveal the answer
Answer: Cruising Sailboat — 10 m. A cruising sailboat measures 10 m (length / span), which is about 1.2× smaller than the reference, a Tyrannosaurus rex at 12.3 m.
A modest cruising yacht is commonly around ten metres long.
Common miss: players tend to inflate a cruising sailboat when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
How long is a rescue helicopter compared with a Spinosaurus?
Reveal the answer
Answer: Rescue Helicopter — 17.8 m. A rescue helicopter measures 17.8 m (length / span), which is 1.2× as big as the reference, a Spinosaurus at 15 m.
Most of the length is tail boom — the cabin itself is barely longer than a van.
Common miss: players tend to compress a rescue helicopter when it sits beside a Spinosaurus — big things get squeezed, small familiar things get stretched.
