On August 6, 2021, it was announced that Justyna Steczkowska, Tomson & Baron, Sylwia Grzeszczak and Marek Piekarczyk would become the coaches for the twelfth season of the show. On August 11, 2021, Tomasz Kammel and Maà Âgorzata Tomaszewska confirmed that they would return as the hosts for their eleventh and second season, respectively.

The blind auditions began on September 11, 2021. Each coach has two "blocks" to prevent another coach from getting an artist with only 2 blocks permitted to be used per blind audition. Each coach ends up with 12 artists by the end of the blind auditions, creating a total of 48 artists advancing to the battles.
Marek pressed Justyna's button.
The battles began airing on October 16, 2021. In this round, the coaches pick two of their artists in a singing match and then select one of them to advance to the next round. Losing artists may be "stolen" by another coach, becoming new members of their team. Multiple coaches can attempt to steal an artist, resulting in a competition for the artist, who will ultimately decide which team they will go to. At the end of this round, seven artists will remain on each team; six will be battle winners, and one from a steal. In total, 28 artists advance to the knockouts.
Due to health conditions Adela Konop was forced to withdraw. As a result Wiktoria Bià Âczyk sang with her coach, Marek Piekarczyk.
The Knockout round will premiere on November 6, 2021. During this stage, all contestants have to sing - the first four from each team are automatically put in the hot seats, and after subsequent performances of the remaining three, the coach decides whether a given contestant stays in the show or not. In the end, four contestants from each team qualify for the live episodes.
The Live shows began on November 13, 2021. When the teams consist of four contestants, the coach chooses from among the two contestants with the fewest votes from the viewers (who decide by sending text messages) the person who drops out of the program. Each live episode ends with the elimination of one person from each group. In the semi-final (when the team is made up of two people), each coach divides 100 points to their artists in any way they want. The same happens with the viewers' votes, and the artist with the most points added passes through to the Final.
