Button Men is a dice game for two players, invented by James Ernest of Cheapass Games and first released in 1999.Games are short, typically taking less than ten minutes to play. Each player is represented by a pin-back button of their choice. Buttons are metal or plastic discs, about 2–2.5 inches (about 5–6.5 centimeters) in diameter, with a pin on the back that can be used to fasten them to clothing.
