"Toby was teaching Nick and Wani how to play boules"

 Boules is the name given to a number of games in which the objective is to throw, or roll balls as close as possible to a target-ball.

In the South of France, boules is another name for the game pétanque. In pétanque, participants stand inside a starting circle and throw hollow metal balls as close as possible for a small wooden ball known as a cochonnet.

It is is an extremely popular game in France, especially amongst people who are on their summer holidays. The playing area is usually hard-packed dirt or gravel, but boules may also be played on sand or grass.
