Round One: Open Auditions - A random judge listens to a cappella rap. The rapper passes to the next round if he/she receives a SMTM necklace from the judge.
Round Two: One Minute Rap - Rappers have one minute to rap to a beat of their choice for an entire minute in front of all the judges. At least one judge must pass the rapper in order for the rapper to move on to the next round. However, if all four teams fail the rapper, the rapper is eliminated from the competition.
Round Three: Rap Battle - Rappers are randomly selected one by one to choose an opponent for a 1v1 rap battle. The rappers are given time to choose a beat and prepare for the battle before they perform it in front of the judges. The judges will then choose one rapper to move on to the next round; the other rapper is eliminated.
Revival Round - Four rappers are chosen from the losers of the previous round and must compete in another 1v1 rap battle. Two rappers are chosen from the four to move on to the next round.
Round Four: Guerrilla "Cypher" Mission - All of the rappers must participate in a cypher and four of them are eliminated. Snoop Dogg was the guest judge for this round. The rest are part of the Top 24.
Round Five: Team Choosing - All of the judges put on a performance for the Top 24; the team with the most votes from the contestants gets to choose four rappers to be a part of their team. After that, the remaining twenty rappers choose which team they want to be a part of; if a team has less than four rappers in the room, the team is automatically eliminated. If there are more than four rappers in the team room, the judges of that team must eliminate the excess amount of rappers down to four rappers.
Round Six: Official Song Mission - Each team puts on a performance for all of the judges and then one rapper from each team is eliminated.
Round Seven: Team Diss Battle - Two teams are pitted against each other and the losing team has to eliminate one rapper. All three rappers from the winning team advance to the next round.
Round Eight: Live Performances - The first place rapper within each team(chosen by each of the producer teams) gets to have a live solo performance. Based on the money earned during the performances, the contestant with less money earned would be sent home(if the contestant was the last of his producer's team, the team cannot participate in the battles any longer).
Round Nine: Live Performances - The winners of the previous round were put together based on the producers' choices. Whoever earned the least amount of money would be sent home.
Final Round: Live Performances - The finalists get to have a final performance to determine the winner(based on how much money is earned).
Team Brand New: Basick, Microdot, Black Nut (Black Nut was brought back in Hanhae's place after the judges believed they made a mistake eliminating him in favor of Hanhae.)
