Rules for 3v3 Floorball Tournament:

1. Team Composition:

• Players: Each team consists of 4 players (3 outfield players and 1 goalkeeper).
• Teams: Each can have maximum of 7 players.
• Substitutes: If allowed, they can happen at any time. 

2. Match Duration:

• Game time: Matches are typically played in 3 thirds of 5 minutes each, depending on the tournament format, with a short break in between.
• Overtime: There are no overtimes.

3. Playing Area:

• Court size: The playing area is smaller than a full-sized floorball rink, usually around 20m x 10m or a similar size suitable for 3v3 games.
• Goals: The goal area is smaller, and goals are typically 1.6 meters wide by 1 meter high.

4. Start of Play:

• Faceoff: Games start with a faceoff in the center of the court. The same applies after goals or stoppages in play.

5. Scoring:

• Goal: A goal is scored when the ball completely crosses the goal line between the goalposts.
• No offside: In 3v3 floorball, there is no offside rule, so players can move freely across the court.

6. Rules for the Ball:

• Ball handling: Players cannot carry or hold the ball with the stick for more than a few seconds (usually around 3 seconds).
  Stick height: Players should not play the ball above knee height.
• Fouls: High-sticking, body checking, and dangerous play (like slashing or tripping) are generally penalized.

7. Goalie Rules:

• Goalkeeper restrictions: The goalkeeper can use any part of the body to stop the ball but cannot play with the stick outside of the crease area (the goal area).
• Goalkeeper movement: Goalies cannot leave their crease (or may have restricted movement outside it) depending on tournament rules.
• Goalkeeper possession: The goalkeeper is usually allowed to hold the ball for no more than 3 seconds before releasing it back into play (similar to other floorball formats).

8. Penalties:

• Minor fouls: Common fouls result in a 2-minute penalty, where the offending player must serve the penalty off the court.
• Major fouls: Serious fouls (like dangerous play) might result in a 5-minute penalty.
• Penalty shots: Some tournaments may call for a penalty shot in the event of a foul that prevents a clear scoring chance.

9. Substitutions:

• Dynamic subs: Substitutions are generally made during a stoppage in play or when the ball is out of bounds. Substitutes must enter and exit at their team's designated substitution area (if there is one).

10. Conduct:

• Fair play: Sportsmanship is essential, and teams or players showing unsporting behavior may be penalized or disqualified from the tournament.
