The Game:
Four children stand in each one of the four service courts on a tennis court.
They are assigned the following characters. King/Queen, Prince/Princess, Knight and HOBO.
The King or Queen serves the ball over the net. The rally goes back and forth until someone misses.
If the knight or the HOBO miss, they trade places.
If the King/Queen or Prince/Princess miss, everyone moves one position anti-clockwise.
That’s it. Enjoy.
