Group Stage The twelve teams are drawn into three sections of four teams, with each section containing three county teams and one university team. Each team plays the other teams in their section once, either home or away. Two points are awarded for a win and one for a draw. The points-ratio method is used to determine the ranking of teams who are level on section points. Knock-out Stage The winners of the three sections and the best of the runners-up in the three sections compete in the semi-finals with the two winners meeting in the final.
Experimental rules
On 24 November 2018 the GAA Central Council approved five experimental changes to the football playing rules which were amended slightly and trialled in the 2018–19 early season competitions organised by the four provincial councils. The rules trialled were –
The maximum number of consecutive handpasses allowed is three.
A sideline free must be kicked forward except when it is inside the opposing team's 20 metre line.
An advanced mark may be taken where the ball is kicked in the area outside the opposing team's 45 metre line, travels more than 20 metres, and is caught cleanly without touching the ground in the area inside the opposing team's 45 metre line by an attacker or a defender. Up to fifteen seconds are allowed for the free resulting from the mark to be taken.
Ten minutes in a sin bin without replacement is imposed on a player who commits a black card offence. The offending player can re-enter the game or be substituted after the ten minutes have elapsed.
Kickouts must be taken from the 20 metre line but are not required to travel beyond the 45 metre line.
The effectiveness of the new rules was reviewed by Central Council on 19 January 2019. Although one of the key aims of the experiment was to reduce the number of handpasses in gaelic football, they voted 25-23 to not continue with the rule that restricted the number of consecutive handpasses to three. This decision followed an almost universal campaign by GAA county team managers in the media against its permanent introduction The Gaelic Players Association were also strongly against the three handpass rule. The remaining four experimental rules were trialled in the 2019 National Football League which began on 26 January 2019 and ended on 31 March 2019. There was little criticism of the four rules in the league games. Jim Gavin, the Dublin manager, said the decision to experiment in the league, the GAA's second tier inter-county competition, was "disrespectful". GAA rules only allow changes to the playing rules in years divisible by five which means that, at the earliest, the experimental playing rules could only be approved by Congress 2020 for implementation in the 2020 Championship. The three handpass rule was not used in the Dr. McKenna Cup final. Both Tyrone and Armagh agreed to play without the rule as it had been abandoned by Central Council in the hours just before the final.
