This is followed by a second roundtable of discussion.
Then, each of the male contestants eliminates a female contestant of the other group.
Most episodes commonly feature a themed format, often involving the contestants (and often, host Penelope Menchaca, as well) in costume; themes used on 12 Corazones include beach-themed episodes in which contestants appear in beachwear, and a beauty pageant-style themed episodes, among others.
After their introduction, the males interact in a mock play, or they are asked to perform a stunt, usually for their ridicule (sing a song, recite a goofy poem, etc.) Then, the host begins a roundtable of discussion on a certain subject.
This leaves only three contestants in the main group and five contestants on the group of suitors.
For the final segment, the host picks a contestant of the second group who is supposed to pick their heart among the male or female contestants.
On the second segment, a chosen male or female from the main group is eliminated.
The contestant chosen has the option to accept or reject.
The rules of the show allow the contestant of the second group to pick their heart among the contestants from the first group who have already chosen another person from the second group (an example occurred in an episode originally broadcast on January 20, 2011, in which the same male contestant was chosen by each of the five remaining female suitors; the male contestant chose each of the females, effectively rejecting the previously chosen females in the process, also as per the rules of the show).
As the show is aimed at women, the host is most exaggeratedly on the female contestants' side.
She often mocks the men, baits them to make them look dumb, and praises the ladies when they ridicule them.
