The practice of coin flipping dates back to ancient Rome, where it was called "nia aut caput" (ship or head), referring to the two sides of Roman coins. The Romans used coin tosses to settle disputes and make important decisions.
Throughout history, coin tosses he been used in sports, politics, and daily life. Famous coin tosses include the start of football games, determining which team gets first possession, and even deciding the layout of some cities. The phrase "heads or tails" became standard as coins typically featured a ruler's head on one side.
Today, coin flipping remains one of the most universally recognized methods of fair random selection, now enhanced by digital technology for perfect randomness.
