* No Offsides
Play is free-flowing — offsides don't apply here.
* No Goalkeepers
Every player is a field player. No one can stay in goal.
* Team Size
    Max 6 players per team
    Min 3 players to start or continue a game
    Sub anytime when the ball is out (rolling subs)
* Game Time
    Games are 20 minutes total
    Each game is 20 mins in length - no halves
    Ties are OK in group stage
    Knockout games go straight to penalty kicks if tied (3 per team, then sudden death)

* Shoes: You can wear cleats or indoor shoes
* Shin Guards: Not required, but smart to wear

* No Slide Tackling — it's a foul
* No Goalies — no camping in front of the goal
* No Fighting or Yelling at Referees — you’ll be kicked out
* Too Rough? — Refs can give yellow/red cards
    2 yellows = red card = you're out
    1 red = you're out immediately
