It is bigger variation of the original Marble Castle. The 10-mm ball runs from the top center all the way down to the front gate in over 60 seconds. The design has several castle-like features: a big tower in the middle, walls around, four corner lookouts, two court yards, a front gate, a back gate, a balcony and a church. One feature is the question-mark shape at the top. This is a tribute to Adrian Fisher, who has included a question mark in several of his maze designs. This marble track was 3D-printed by Ivan Danik (a.k.a Puzzle Guy), using 3138 gram of marble filament. It took 95 hours and 11 minutes to 3D-print, which is almost four full days. So four days of work for 60 seconds of rolling fun :-) Copyright (c) 2025, M. Oskar van Deventer.
