Rokr Marble Travel London 3D Wooden Puzzle (431 Pcs) builds a small London cityscape where the marble triggers the Big Ben chime, crosses Tower Bridge over the Thames and is lifted by a rotating wheel to start again.
Why it is listed here
Where many marble runs are abstract machines, this one tells the story of a city tour, which gives it more to look at when it is standing still. It is also compact for a motorised run at under 9 inches wide, and the parts lock together with mortise and tenon joints, so there is no glue to manage.
What the build involves
The listing mentions a motor but does not spell out the power source, so check the box contents before you start. Build the tracks slowly and make sure every diverter moves freely; one stiff joint is enough to stall a marble. Give it a level, stable spot with room above for the wheel so the loop runs cleanly.
