发明名称 Set of display matrices
摘要 The set comprises a plate (1) in which are incorporated four matrices (M1, M2, M3, M4). The matrices are of the seven-segment type and are each formed by a cutout in the shape of an "eight" in which the players can insert seven segments at most (2, 3) of contrasting colours. These segments may be arranged on the matrices so as to form numbers, letters or symbols. <IMAGE>
