The term GAME WITH IT? can be solved by the three letter word TAG. TAG is a game that has been played for centuries, and is still popular today. It is a game of chase in which one person is 'it' and must chase the other players, attempting to TAG them. The player who is 'it' must try to TAG the other players before they reach a designated safe spot. The game is often played outdoors, but can also be played indoors.
