Abstract: An electrical version of the game Tick-Tack-Toe comprises a stylus-actuated switching device including a printed circuit board carrying one group of electrically-conductive deposits, and an overlying flexible plastic sheet formed with a conductive layer facing the conductive deposits of the printed circuit board but separated therefrom by a wax coating carried either on the printed circuit board or on the flexible sheet. Both the sheet and the board are divided into a 3 .times. 3 matrix of 9 boxes, the electrical conductive deposits of the printed circuit board being arranged so that if an 0 mark is traced by the stylus in any box, a first electrical switch is closed by causing the wax to part and one deposit on the board to engage the conductive layer on the flexible sheet, and if an X mark is traced by the stylus in any box, a second electrical switch is closed by causing the wax to part and another deposit on the board to engage the conductive layer on the flexible sheet. The game further includes an electrical circuit effective to provide a first indicatio (e.g., the X-marker wins) when the first electrical switches of the three boxes in any horizontal row, vertical column or diagonal are all closed, and a second indication (e.g. the O-marker wins) whenever the second electrical switches of the three boxes in any horizontal row, vertical column, or diagonal are closed.
