     Children have their own rules in playing games. They seldom need a referee and rarely trouble to keep

scores. They don't care much about who wins or loses, and it doesn't seem to worry them if the game is

not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be directly

compared. They also enjoy games that move in stages, in which each stage, the choosing of leaders, the

picking-up of sides, or the determining of which side shall start, is almost a game in itself.

     Grown-ups can hardly find children's games exciting, and they often feel puzzled at why their kids play

such simple games again and again. However, it is found that a child plays games for very important reasons.

He can be a good player without having to think whether he is a popular person, and he can find himself

being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to

his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be

dead, to throw a ball actually at someone, or to kiss someone he has caught.

     It appears to us that when children play a game they imagine a situation under their control. Everyone

knows the rules, and more importantly, everyone plays according to the rules. Those rules may be childish,

but they make sure that every child has a chance to win.
