Buzzer format

A format similar to the Got Talent franchise and used on earlier phases of the competition, each judge in a panel of five has a buzzer to light up during a performance. When the contestant received at least three buzzer hits (but not all five), their performance is suspended. If the contestant did not receive all five buzzer hits, the judges may entitle a contestant an additional 30-second "encore performance", otherwise the contestant is eliminated immediately. The contestant advances if they received less than three buzzer hits at the end of the performance (and during "encore performance" if applicable), but the contestant is eliminated if the contestant still receive at least three buzzer hits after the "encore performance". In some seasons, each judge has one "save" to use, to save a contestant from elimination.

During seasons six and seven, the number of judges is reduced to three and now requires no more than two buzzer hits to advance; getting two buzzer hits suspends the performance, and a third buzzer eliminated the contestant immediately.

Score scheme

Commonly used in each round, performances are determined by scores given by the judges. Each judge is allowed to give each contestant up to 10 points, with a maximum score of 50. In season eight onwards, the judges' maximum score is 20, with a maximum total score of 100.

For the first season, the total score was shown in integer, but due to the possibility that multiple contestants received the same scores, the later phases of the season were adjusted to include one decimal point. Beginning from the second season, the judges are no longer individually giving the contestants a score, but all at once, making the scoring system relevant as well.

Usually, the contestants, and if any, who received the lowest scores are eliminated from the competition. For weeks with a double-leg, the contestant with the lowest combined scores from both weeks is eliminated.

Cumulative scoring round

For the first five seasons, once the competition is down to six are finalists, these contestants will have to undergo four rounds for the champion title. Scores from the rounds are cumulative and weighted in favor of each episode (10%-20%-30%-40%); after three rounds, the contestant with a lower combined score is eliminated, and after all the rounds have been performed, the contestant with a higher combined score is named the season's winner. The Cumulative scoring round is similar to the one round of the same name in another Chinese show One Million Star and Chinese Million Star, but with a different format (scores are not weighed until the second round of the finals).

Battle round

Battle rounds are also common in each round whereas contestants competed head-to-head for survival. Winners on each battle are decided by a vote, and the contestant receiving a simple majority of votes wins the battle and are safe from elimination. The rules for the battle rounds vary on each season format:

• For the first four seasons, the judges will vote for the contestant for the better performance; the contestant to receive a simple majority of three votes wins the battle.
• In some episodes with six judges, four votes is required for the win; if the judges were tied with three votes each, both contestants advances instead.
• For seasons five and seven, some of the battles were adjusted to three contestants. A contestant requires at least two votes to win; a battle may produce either one or two winners.

Category format

Exclusive in the seventh season as a theme between campus and community category, similar to Project SuperStar (where the categories are gender-based) and earlier versions of The Voice, eliminations applied with an equal number of contestants from each category. Categories are dissolved beginning with the Top 20 (10 from each categories), meaning that eliminations are now applied disregarding to the category's affiliation. A similar variant also applied on the eighth season, but categories are based on the recording labels and only the top contestants are allowed to be in the category.

Returning champions format

Exclusive in the final season, the season's format was changed to an arena-style. Six new contestants each week compete in one round of song and the contestant whose scores are among the top three (12 new and six advances in the premiere week) will advance to the second round of the show; if there are more than one contestant tied with the third-highest score, a sing-off happen after the round and judges vote on who to advance. In the second round, a contestant competed head-to-head and the contestant with a higher score in each duel will become a champion; in the event of tie, a sing-off will be held on the following episode with scores reset.

Incumbent champions will compete in subsequent episodes with no option at bail out; for every challenge won, the champion wins NT$10,000 per winning streak with an option to quit at every 10 challenges; if the champion wins 25 challenges, the champion will retire and their winnings was augmented to NT$300,000.
