It is a game in which two teams
basically try to capture each other's flag while defending their own using
compressed-air guns that shoot paint-filled balls. There are many variations of
the game that can be played.
It's very common for players to feel a slight sting, like a firm flick on the arm. The pain is minor and typically fades quickly. While most hits are insignificant, a paintball can cause bruises and welts.
