This activity is a tag variant often played with children. One or more players are designated as the predators, while the remaining players are the prey. The prey line up on one side of a playing area, and the predator(s) stand in the middle. When the predator(s) call out a signal, the prey attempt to run to the opposite side of the area without being tagged. Those who are tagged become predators for the next round.
The activity promotes physical activity and agility. Historically, it has been a common recess or physical education game, providing a simple and accessible way for children to engage in exercise and develop fundamental movement skills. Its inherent simplicity makes it easily adaptable for various age groups and playing environments.
