Abstract: Described herein are games and game systems including a text messaging phone keypad foot mat. The phone keypad foot mat typically includes regions similar to the buttons of an enlarged telephone keypad. A user can step on these input regions (“buttons” or “keys”) to type a text. Thus, a player “types” a text message by stepping or dancing on the keyboard foot mat similar to the way that a text message may be typed by hand on a telephone keypad (e.g., sending a text message from a cell phone). Various games can be played using the devices, systems and methods described herein.
