Chase and catch games have always been popular with children all over the world. In Singapore, it’s commonly known as Police and Thief. The rules are simple. Thieves run while the Police catch.
There’s a homebase for the Thieves and a jail for the Police. Thieves get immunity by staying in the homebase but it is generally considered cowardly to stay in there for a long time. This game was a favourite activity during recess and probably the reason why so many children end up sweaty and dirty at the end of a school day.
