2015 witnessed a further series of Intervilles International which had been running since 2005. This year, five national teams competed over two rounds of six heats, with national winners declared after Heats 6 and 12, with an International Final, after which the year's biggest prize was awarded to the national team with the highest aggregate score across all 13 events. Teams from France and Hungary, fresh from their participation in the 2014 series, were welcomed back, along with China and Kazakhstan, who had both last competed in Intervilles International in 2013. The line-up was completed by competitors representing Algeria, a country brand new to Jeux Sans Frontières-related events. Teams were each composed of 30 players, and the team captains could choose which competitors played which games.

The events were staged in China's Hainan Island, a territory nicknamed the Chinese Hawaii. As in the 2014 series, the International Referee was Olivier Grandjean, who again also presented the winners' trophy in each edition and the final.

The programmes were originally planned to be staged in the period Saturday 18th April to Friday 8th May 2015, but plans were changed and the recordings actually took place between Mondays 8th and 22nd June 2015. No recordings took place on Sundays.

One welcome revision compared to previous seasons was that in 2015, the Champions' Wall event was altered to a points-scoring event rather than a 'winner takes it all' game. This was a decision almost certainly arrived at due to the Russian teams' almost complete domination of the Champions' Wall in the 2014 regardless of the points totals they had amassed.

Scoring was, however, harsh, with no points awarded for teams finishing in 4th and 5th place on any game. This was ameliorated very slightly by an unusual approach to awarding points in the event of a tied placing on a game, with the teams finishing below a tied placing being designated as finishing in the position directly below, with the points for that position awarded (e.g. a team finishing below a tied 1st place was given as 2nd rather than the expected 3rd place).

Teams missed one game each, either Game 2, 3, 4, 5 or 6. In another diversion from the norm, it was possible for teams to choose which game to avoid, and this choice would be made by teams after Game 1, with the 1st place team getting the first choice, 2nd place second choice, and so on. Consequently, Game 1 was a very important game, with its winners able to absent themselves from the game they were least good at.
