The maze shall comprise 16 x 16 multiples of an 18 cm x 18 cm unit square. The walls constituting the maze shall be 5 cm high and 1.2 cm thick. Passageways between the walls shall be 16.8 cm wide. The outside wall shall enclose the entire maze.
The sides of the maze shall be white, and the top of the walls shall be red. The floor of the maze shall be made of wood (plywood) and finished with non-gloss black paint (black-board paint). (The brand and color numbers of paints shall be declared).
Caution: Do not assume the walls are consistently white, or that the tops of the walls are consistently red, or that the floor is consistently black. Fading may occur. Parts from different mazes may be used. Do not assume the floor provides a given amount of friction. It is simply painted plywood and may be quite slick.
The start of the maze shall be located at one of the four corners. The starting square shall have walls on three sides. The starting square orientation shall be such that when the open wall is to the "north", outside maze walls are on the "west" and "south". At the center of the maze shall be a large opening which is composed of 4 unit squares. This central square shall be the destination.
Small square posts, each 1.2 cm x 1.2 cm x 5 cm high, at the four corners of each unit are called lattice points. The maze shall be constituted such that there is at least one wall touching each lattice point, except for the destination square.
The dimensions of the maze shall be accurate to within 5% or 2 cm, whichever is less. Assembly joints on the maze floor shall not involve steps greater than 0.5 mm. The change of slope at an assembly joint shall not be greater than 4. Gaps between the walls of adjacent squares shall not be greater than 1 mm.
Multiple paths to the destination square are allowed and are to be expected.
