The league followed standard American football rules, with two exceptions. Field goals of over 50 yards were awarded four points instead of three, as in NFL Europe. The league also offered a three-point conversion from ten yards, just as the original XFL did in its playoffs. These rule changes were intended to help teams that fall behind in a game to catch up more quickly. The league did not use instant replay. The league also used a slightly shorter play clock. Teams were restricted to 35 or 36 players on each roster, with any person 18 years of age or older eligible to play. Its level of play could be classified somewhere between minor league and semi-professional; players were compensated between $100 and $500 per game, on par with most indoor football leagues, but had to pay their own travel expenses for away games.
Teams
2011 season
The League awarded charter memberships to eight cities in seven states. Teams were awarded to Las Vegas, Little Rock, Pontiac, New Orleans, Mobile, and Charleston, along with Daytona Beach and Fort Lauderdale. For reasons unknown the Las Vegas Gamblers, Little Rock Ironmen, Charleston Admirals and the Mobile Gladiators never made it to play; the Ironmen, in particular, have been the subject of repeated relocations. The Michigan Coyotes, having a much greater distance between themselves and the rest of the league, were declared a traveling team for their two games in the 2011 season. Had any home games been scheduled the team was to play at the Silverdome. Fort Lauderdale played its first season at Lockhart Stadium and Daytona Beach at Municipal Stadium. The league released on July 2, 2011; said schedule was abruptly cut short in early August after several on-the-fly schedule and venue changes. In the end, each of the four teams played two of the other three teams at least once, with Daytona Beach and Fort Lauderdale playing each other three times, due to their proximity to each other. Winners of each game are underlined.

2012 season
The 2012 season was originally scheduled to begin on Armed Forces Day and continue through July; although a northern division was originally planned in addition to the Florida teams, neither of the two new proposed teams meant to complement the existing Michigan Coyotes would form, eventually forcing the Coyotes' mothballing. New Orleans left the league and joined other semi-pro leagues. In Florida, the SFL also proposed a team named the "Orange" and a team based at South County Stadium in Port St. Lucie, neither of which came to fruition; likewise, the plan to play a game in Freeport, Bahamas's Grand Bahama Stadium also never occurred. In the end, of the roughly eight teams originally announced as participants in the 2012 SFL season, only three would make it to play: Daytona Beach and Fort Lauderdale, in addition to the Fort Myers Swampdogs, who played the season at Bishop Verot High School. Daytona Beach's lone home game would be held at Lawnwood Stadium in Fort Pierce. The season finally began on June 9, 2012, with a matchup between Daytona Beach and Fort Lauderdale in Fort Pierce. Fort Lauderdale won the contest on a last-second field goal, by Garrett Ewald of Coral Springs. Fort Myers played its first game June 16.

2013 season
After numerous proposals and another erroneous draft schedule was released in the 2012-13 offseason, by the time of the April 2013 training camps the league had settled on an expansion to four teams for the 2013 season, adding the Miami Ironmen. The league began play on June 8, 2013 with a baseball-style doubleheader in Fort Lauderdale. Two days before the start of the season, the league also announced that all six of the SFL's scheduled games for 2013 will take place at Central Broward Regional Park. The Swampdogs were nonetheless renamed the "Pompano Swampdogs" despite no connection to that city; likewise, the league made no effort to relocate the Daytona Beach Racers back to its namesake city, although the team's head coach continued to send news reports to the local newspapers there. The schedule is single round-robin, with each team playing each other once.

Resolution
The team formally dismissed all of its coaches in February 2014 and has since ceased public operations; the league released a draft schedule that was to begin the 2014 season in April, but the schedule was removed after none of the games were played and the 2014 season was silently canceled. Commissioner/owner Peter Hulthwaite announced the league's assets were up for sale on August 24, 2016.
