GeTai Challenge (season 2)

The first two shows were taped at MPC@Khatib on 6 April 2018, showcasing all the singers' (nine from Season 1 and 20 from Season 2) performances.

This is the first show of the season to be taped at Mediacorp Studios at 1 Stars Avenue. For the next two weeks, 20 singers were paired up and performed with one of nine Season 1 singers (Leon & Febe paired with four singers instead of two) to vie for the 10 spots in the next round. The result was decided solely through judges' votes; judges cast their vote through their tablet device by flashing either one of the three Heng Ong Huat logos. Singers receiving all three judges' votes would directly advance to the top 10, but singers receiving only one or two judges' votes will land them into Pending Zone, where they were eligible to be saved from the judges' immunity (each immunity may be used once on each show). Singers either receiving no judges' votes or were not saved by the judges from the Pending Zone, will be eliminated from the competition.

Starting from week six, the ten singers will be judged based on their performance and assigned a score, based on Costume, Performance, Presentation (20 each) and Singing Techniques (40). The scores were accumulated until week nine, and the singer receiving the lowest cumulative score afterwards will be eliminated from the competition. For the next four weeks, Jim Lim was absent in his judging role due to work commitments; Mediacorp actor Cavin Soh took his place on the panel.

The round was split into two episodes with the ten singers assigned into two groups of five. For this battle round, a singer would be sent by his or her teammates to compete against another singer from the opposing team. The selection of the singer and their order of appearance were all decided by their respective teams, and all of which were done without the knowledge of the opposing team. Therefore, the pairings were completely by random, and would only be revealed when the teams revealed their selection on stage. The order of the matchup were done through Rock–paper–scissors, and the winner earned the right to decide the order. At the end of each match, the judges will cast their vote to which singer they liked the most, but those votes does not necessarily affect the outcome of the competition. At the end of all five matches, the group with a higher combined total (based on this round) will directly advance to the next round, while singers from the losing group were eligible for elimination based on the combined scores received from both rounds. FLY Entertainment artist Irene Ang was brought in as the guest judge.

For the next three weeks, the top nine singers faced head-to-head against the Season 1 singers; both the order of performance and their match-up were determined by ballot, with the Season 1 finalist performing first. The results of the battle were not announced until Week 12; victorious singers will directly advance to the top seven rounds; of the defeated singers, the one singer which was not saved by the judges will be eliminated, while the other singers will have to sing again on the Breakthrough round next week. The scores were not used for the results, and scores for the prior round were reset. Top 20 finalist Xie Wen made his cameo appearance during Week 12 episode.

The next two shows were taped at the open field near Arumugam Road at MacPherson for a crowd of 1,200 people. In this round, the five singers who were defeated in the top nine rounds performed for a chance to stay in the competition. The order of performance was decided by the judges. For this week, in addition to the four scoring components, a fifth component, "Breakthrough Index" was added, and each component carries a 20-point weightage. The singer with the lowest score will be eliminated from the competition.[17]

The top seven performed on this week for a spot in the semi-finals. The order of appearance was decided through the drawing of lots. In deciding who moves on, the three judges; as well as the studio audience made up of 300 members of the public were given an equal say. Each of the voters was entitled to one vote per singer, and they can either choose to vote or not vote for a particular singer. The scores from the judges, as well as the total number of votes cast by studio audience converted into points accordingly to the percentage of the valid votes cast. The singer with the lowest accumulated total points would be eliminated from the competition.[18]

The Semi-finals was split into two episodes, with the entire first round and the first two singers from the second round performing on the first episode, and the last four on the second episode. In the first round, six singers received their paper cutouts from the producers, which determined their pairing and performance order; the scores for this round (which include Team Chemistry; each component now have a 20-point weightage) were judged based on the duet itself, rather than judging individually (meaning both singers from the same duet were given identical set of scores). In the second round, judge Jim Lim handpicked six songs for the singers to choose from (with the order of choice based on their placement from the Popularity round), and work on a song mixed with two genres  – original and designated, with the latter unknown to the contestant's knowledge until the start of the round. The scores for both rounds were combined and calculated by average; normally, the two singers receiving the two lowest scores would be eliminated from the competition; however, after two singers (Angie Lau and Cola Lau) were tied for fourth place, both singers were advanced to the Grand Finals. Director of Getai musical film 881 and music video "大家兴旺发" Royston Tan was brought in as the guest judge.

The Grand Finals were taped on 26 July 2018 and broadcast on a two-hour special starting at 10.30am. In the first round of the competition, the five finalists performed a duet with celebrities (if any). Based on the judges scores (40 for singing techniques, 30 each for stage presence and presentation) in the first round, the bottom three singers with the lowest judges' score would be eliminated.

The final two singers would then sing their winner's song in the second round of the competition; the singer who received the highest total combined score was announced as the winner. Actor Cavin Soh and guest singer Daniel Luo were brought in as the guest judges. Senior Minister of State, Information and Communication & Culture, Community and Youth, Sim Ann, was the guest-of-honour for the finale. A special teaser for the talkshow The Love 97.2 Breakfast Quartet - Listen To Me (which premieres the week after) was shown during the closing of the show.
