Children all sit in a circle. One child is selected to crouch in the middle and act as the “sleeping giant”. They take a set of keys (or any other similar object with them) and place these behind them. Whilst they are in the middle of the circle with their eyes closed, a “thief” is selected from the surrounding circle to go in and steal the keys.
The thief must move their chair out from the circle first and then tiptoe behind the giant to steal the keys. When they have the keys in their hand, they must run out of the circle (there should be a gap where they removed their chair from) and run around the outside as fast as they can and finally back into the middle through the same gap they came out of without the giant catching them.
The giant may only start chasing when they hear the keys being snatched. If the thief is successful, then they become the giant. If not, the giant remains the same.
