DOUG SOLUTIONS Inside3 Vicious0 cube maze brown

The Inside3 Vicious0 is a three-dimensional labyrinth in the form of a cube, played entirely blindfolded. A ball rolls inside the cube and is only visible from below or above, depending on where it is within the structure. Each side carries a map of seven sections that the player must guide the ball through. The game combines logic with hearing and touch, so you rely on sound and the feel of the movement rather than sight.

Vicious0 is the fifth step in the 0 cube series and is aimed at more experienced players. Its base is welded to the cube, so unlike its predecessors it cannot be taken apart. If the ball falls out, it is lost and has to be retrieved somehow.

The cube measures 6 x 6 x 6 cm and weighs 150 g. It is designed for indoor use and, according to the manufacturer, suits teenagers.
