The rules of play evolved as the years progressed, and the following summary refers to the rules used during the final competition in 1993.
- A specially constructed artificial field, measuring approximately 200′ by 85′, with perimeter walls topped with acrylic glass to a height of 7′ was used. Goals were set into the walls.
- Squads consisted of up to 12 players, with no more than 6 on the field. Substitutions were unlimited and could be made at any time.
- Matches were played in 2 halves of 7 minutes 30 seconds during the first round and 2 halves of 10 minutes during the knockout stages. At the end of all tied matches, even during the group phase, a penalty shoot-out would be held. A win on penalties in the group phase was worth 2 points as opposed to the 3 gained by winning after regulation time.
- Two yellow lines separated the field into thirds. Players had to be inside this line in order to shoot on goal, and a three line pass rule (similar to ice hockey’s two line pass rule) was in effect.
- The goal area at each end was reserved for the sole use of the goalkeeper defending it. If an outfield player from the same team infringed on it a penalty kick would be awarded to the opposing team.
- Goalkeepers could only hold on to the ball for six seconds. This was a particularly interesting situation as FIFA would later adopt this rule for conventional association football.
- Teams were required to maintain a presence of at least 2 players in the opponents’ half (1 player prior to 1991) or a penalty kick would be awarded to the opposing team.
- Players shown the yellow card would be dispatched to the Sin Bin for 2 minutes.
