1. 

The game is played by 2 teams of 1, 2, 3
or 4 players.
Teams of 1 or 2 players use 3 boules per
player. Teams of 3 or 4 use 2 boules per player.

2. 

Toss a coin to choose
which team will start.
A player on this team chooses the starting point by drawing a circle of about
20 inches (50cm) in diameter. 
3. 

This player tosses the
little target ball
between 18 and 30 ft ( 6 to 10 meter ) away, but not closer than 20" (50cm) from any
obstacle.
The thrower's feet must stay inside the circle until the jack has reached the
ground. 
4. 

Any player from this team then throws the
first boule, trying to place it as close as possible to the target ball.
Again, both feet must remain inside the circle when throwing. 
5. 

A player of the second team comes into
the circle and tries to throw a boule even closer to the target ball.
Or knocks away the
first
team's leading boule.
The boule nearest to the target ball leads. 
6. 

It's up to the team not leading to throw
until they get a leading boule. Then it's up to the other team again.
When
a team has no boules left the other team throws their remaining boules and tries to place
them as close as possible to the target ball. 
7. 

When neither team has any boules left the
points are counted.
Only the leading team scores: as many points as it has boules that are
closer to the target than the best one of the losing team.
In the example on the left, the "blue" team has 3 boules closer to the
target ball than the nearest boule from the "green" team, and thus gets 3 points. 
8. 

An "end" is over when each team
has thrown all its boules. The winning team starts a new end, by drawing a circle where
the previous end finished, and tossing the target ball again.
The game continues until one of the teams has accumulated 13 points.
