A keypad used for dialing telephone numbers to establish a communications link is also used to display game moves. Once the communications link is established between two or more parties, their terminals are placed in a game mode which activates inband signal detection and player identification circuitry located within the terminals. Multi-colored indicators (e.g., LEDs) and player identification displays (e.g., LCDs) at each terminal are activated, their color being dependent upon the source of received instructions. Player identification indicators are incorporated into a touch-tone keypad located on each of the terminals. Each key of the keypad has two or more color-coded indicators incorporated within, each color representing a particular player's move. Thus, the touch-tone keys represent a game board and/or game accessory when the terminal is placed in a game mode. For example, a 3-by-3 matrix formed by the touch-tone keys 1 through 9 of the keypad can be used to play tic-tac-toe over the communications link. The activation of three LEDs of the same color in a row, column or diagonal on the keypad will cause those LEDs to blink on each terminal, signifying the end of the game.
