It was a large-scale project in which the public produces a unit boy group by voting for their favorite members from a pool of 101 trainees from different entertainment companies.

The group would be performing together, under Swing Entertainment and CJ EM (also the label of Wanna One from Produce 101 Season 2 ).

Mnet revealed that the debut group would have a five-year contract.

The first two and a half years of the group, the members will focus fully on the group as a whole.

The final two and a half years, the members will be allowed to do group and individual activities.

This marks the longest contract term to come from the Produce 101 series.

Trainees could battle for the 1 seat and in the end, it was revealed that the trainee who had gotten the 1 seat would have a 1 minute PR time at the end of the episode.

Trainees enter and notice that the seats which were numbered from 1 to 10 only had the debut seat style while the 11th seat was a normal one.

This led to the speculation of whether the number of the members debuting had reduced.

After Lee Dongwook entered, he confirmed that there are indeed 11 members debuting and the concept was 10 X members.

The first 10 is the same as the previous seasons, where they are determined by the ranking in the Final Live Ranking.

But during the Final Live Ranking, the 11th member would not debut, rather X, the trainee the highest number of votes from a total of four voting periods.

Along with this, a new class for grading trainees came forth - X class.

The grades assigned to trainees for their temporary training groups were A (being the highest), B, C, D, and X was the lowest class.

The evaluation began and a lot of trainees were graded X but it is still not known if they were really eliminated or not.

At the end of the episode, a PR video of JYP Entertainment s Yun Seobin was shown and the total votes thus far were shown, Jellyfishs Kim Minkyu was ranked 1.

Trainees begin to train according to their assigned schedule with the mentors.

The trainees would undergo one more final evaluation, in where they are filmed when they are performing X1-MA.

Their re-evaluation grade would reveal their positions and line distributions.

At the end of the episode, the total votes were shown where OUI Entertainment s Kim Yohan was ranked 1.

The trainees filmed themselves performing the X1-MA and these videos were graded by the mentors.

A would be the center group, and F would serve as back up dancers as they have in previous seasons.

Those left in the X class would not be allowed to perform on stage.
