The board consists of a plate with vertical grooves 2 and horizontal grooves 1. The vertical grooves serve as paths leading to the horizontal grooves. The grooves may have a rectangular cross section or a cross section that is otherwise formed. Figures a-b show the cross-section of an embodiment with a groove cross-section other than rectangular. Letter cubes used to form words and sentences must be of a shape appropriate to the shape of the grooves. The mouths of all the grooves are secured with slats 3 against falling out of the individual cubes. The board and the dice can, of course, be made of any suitable material. The cubes are removed from the defined horizontal groove 1 to make room for the sentence. Thereafter, the required letters are shifted in succession along horizontal and vertical grooves in the desired direction. If the road is busy, the cubes in front of the obstacle move to the free space. PL
