Definitions

We will use the following table to refer to the different rods of the foosball table:

Row 1	Goalkeeper (1 foosman)
Row 2	Defence (2 foosmen)
Row 3	Opponent's attack (3 foosmen)
Row 4	Midfield (5 foosmen)
Row 5	Opponent's midfield (5 foosmen)

Tournament structure

The tournament is divided in two phases:

Groupe phase: the teams are divided in groups of two or three teams. Each team meets all the other teams in its group. The worse teams from each group of three teams leaves the tournament at the end of this phase.
Knockout phase: this phase is organized as a single elimination bracket; 4 quarter-finals, 2 semi-finals, 1 final (and 1 additional final to decide the third place).

Organization of games

The first team to score 10 points wins the game.

There is a half-time when the first team reaches five points: the two teams switch sides, and the players inside a team can decide to swap positions (the attacker becoming the defender and vice-versa). Swapping positions during the half-time is not mandatory.

The ball is served by the attacker on the side of the serving hole.

In-game rules

When the ball stops and cannot be reached by any foosman, the action to be taken depends on the position where the ball stopped:

Before the third rod: the ball is put in the closest corner;
Between the third and sixth rods: the ball is served from the middle;
After the sixth rod: the ball is put in the closest corner.

Things you cannot do:

Spinning: swiftly spinning the rods all around without holding them.
Scoring from the midfield directly after serve: the ball must be touched by two of your players from two different rows before a goal. If this happens, the goal does not count and the ball is simply served again from the middle.

Apart from that, everything is allowed, in particular:

Scoring from the midfield during the game;
Scoring from the attack rod without stopping the ball first.
