Yes, Foosball DOES rule ;) but here's how the rules and regulations go:
To Start a Match
A coin flip shall precede the start of the match. The team that wins the flip has the choice of table side or first serve. The team that loses the flip has the remaining option and must also pay for the first game, with that expense alternating thereafter.
Once a team has chosen either the table side or the first serve, they may not change their decision.
In the event of the loser's bracket winner beating the winner's bracket team in the first match, the second match will be started in the same manner as a regular match with the coin flip, etc.
The match officially starts once the ball has been put into play. (BUT violations such as cursing, etc. may be called by the official assigned to judge the match as soon as he and both teams are present at the table.)
The Serve
A serve through the serving hole is used to put the ball into play at the start of the match, after a point is scored, or after a ball leaves the table. The server may attempt to influence the roll of the ball, but may not allow any part of either hand to be in the play area once the ball hits the playfield.
The play area shall be defined as the area above the playing surface to the height of the side boards of the cabinet.
Prior to serving the ball, the server may place either hand in the play area in order to position the ball. However, no part of either hand may be in the play area at the moment the ball is released into play.
If the ball hits the playfield while any part of the server's hand is in the playing area, the serve shall be considered illegal. This includes any finger used to push the ball through the serving hole.
The ball may not be struck by either team following a serve until it has touched the playfield, at which time the ball is considered to be "in play" and the time limits start.
Spinning the ball shall be allowed in order to influence the serve, however, no point shall be scored by the serving team unless the ball is struck by one of the serving team's figures.
The server must not serve the ball until he has the assurance that the opposing team is ready for play to begin. The server can signify that play is about to begin by tapping the ball on the side of the table.
If the server has tapped the ball, and the opposing team is holding their handles, the opposing team shall be deemed to be ready for play (unless they have specially stated before the ball hits the playing surface that they are not ready yet).
On the first violation of any part of this rule, the ball shall be re-served by the original server. Subsequent violations, however, shall result in the ball being put into play by a server of the opposing team.
If the ball is incorrectly served, but the server has not violated any part of these rules, the ball is considered in play. In particular, the player may not reach into the play area to re-serve the ball (see 16).
Subsequent Serves
Following the first serve of a match, subsequent serves shall be made by the team last scored upon. First serves in subsequent games of a multi-game match shall be made by the team which lost the preceding game.
If the ball is served by the wrong team, and the violation is discovered before the ball is scored, play shall be stopped and the ball shall be re-served by the proper team. Once the ball is scored, no protests shall be allowed, and play shall continue as if no infraction had been committed.
If a team receives the serve because the opposing team is being penalized for a rules infraction, and if, after the ball is served, it goes dead or leaves the table and must be re-served, it shall be re- served by the team who originally served it prior to the infraction.
Ball in Play
Once a ball is put into play by the server (see 2), it shall remain in play until the ball is hit off the table, a dead ball is declared, time out is called, or a point is scored.
Ball Off the Table
If the ball should leave the playing area and strike the scoring marker, ash trays, top of the side rails, cabinet ends, or any object that is not a part of the table, the ball shall be declared off the table. The ball should be put back into play with a serve by the team which originally served that ball.
