A 4x4 grid for placing tower-like pieces with internal ramps that can create a slalom for a marble. Initial setups are defined in a booklet of challenges with images showing the orientation and placement of pieces, as well as sometimes the pieces you must place yourself in order to get the marble from the entrance to the red goal cube. This version has been re-imagined for younger solvers, and most of the puzzles feature total freedom as to which pieces need to be placed in order to complete the puzzle. Additionally, every fifth challenge is a "Builder Challenge" in which players can build any maze they want. This version of the puzzle is expected to be used by both a child and a guiding adult.

For each challenge place any chosen pieces or the given pieces such that the marble travels from top to the red goal cube.
