This season was the first one to have a different winner, other than Wayamba Elevens who had won all the previous 3 tournaments. Ruhuna Elevens won the tournament and qualified for CLT20 to be held in India. The fourth season of the Inter-Provincial Twenty20 was to be replaced by the Sri Lankan Premier League. There were franchise teams along with the inclusion of two extra provinces and the tournament was to allow international players to play, however the 2011 Sri Lanka Premier League was postponed due to allegations of corruption and incompetence by Sri Lanka Cricket. The Board of Control for Cricket in India had also decided not to allow Indian players to play in the tournament which later became the primary cause. Ruhuna elevens win their first Inter-Provincial Twenty20 tournament and qualifies for the qualifying stage of the 2011 Champions League Twenty20. Also, this was supposed to be the last tournament before SLPL replaced it in 2012, but due to cancellation of SLPL, it will happen for a final time in 2013.
Fifth season
After the cancellation of 2013 Sri Lanka Premier League due to all eight franchises refused to pay their tournament fee, and also failed to guarantee player payments, Sri Lanka Cricket announced that the Super Fours Provincial T20 Tournament will replace SLPL for this year. The primary concern was to have a team crowned champion and hand them a trip to the qualifiers of CLT20 in India to represent Sri Lanka. This tournament, however, will be 4-team tournament lasting for only 7 matches which is the lowest of all the seasons. This is also the first time that Wayamba Elevens will not be part of the tournament. It will begin on 10 August and will last up to 17 August. All seven matches in the league will take place at the R Premadasa Stadium in Colombo All the teams have been renamed. Angelo Mathews will captain the Basnahira Greens, Dinesh Chandimal the Uthura Yellows, Lahiru Thirimanne the Kandurata Maroons and Lasith Malinga will lead the Ruhuna Reds. Each team plays each other once, before the two top sides qualify for the final.
Sixth season
The sixth and final season of Inter-Provincial Twenty20, was named Super T20 Provincial Tournament by Sri Lanka Cricket. The tournament, comprises 5-teams with new names and logos. The teams, however, categorized according to the district and not with the province, Hambantota Troopers, Colombo Commandos, Galle Guardians, Kurunegala Warriors and Kandy Crusaders. All matches were played in R. Premadasa Stadium. Colombo Commandos won the tournament.
Teams
Teams in the Inter-Provincial Twenty20 were based around representation of the Provinces of Sri Lanka. The first three tournaments hosted six teams including either a schools representative team or a Sri Lanka Cricket representative team. However the fourth season only hosted five teams all representing a province as well as a Combined Provinces team, for those provinces that were not represented by one team and in the last season there were even lesser teams.
