Week 7: Eras Night
Couples performed one unlearned dance representing a different historical era. The couple with the highest score earned immunity from elimination, while the rest of the couples participated in dance-offs for extra points. For each dance-off, the couple with the highest score picked the opponent against whom they wanted to dance; the chosen opponent was allowed to pick the dance style (from cha-cha-cha, foxtrot, or salsa). The winner of each dance-off earned two points. For winning immunity, Nastia & Sasha received a three-point bonus. Couples are listed in the order they performed.

Week 8: America's Choice Night
Couples performed a routine featuring an unlearned dance and song that was chosen by the public, as well as a trio dance involving an eliminated pro or a member of the dance troupe. Couples are listed in the order they performed. Two couples were eliminated at the end of the night.

Week 9: Semifinals
Couples performed one unlearned dance, and a routine coached and styled by one of the four judges. To avoid favoritism, the judges did not score the couple they coached (their absent score is marked by an X below), so the second-round dances received a total score out of 30 instead of 40. Couples are listed in the order they performed.

Week 10: Finals
On the first night, couples performed a dance that they had previously done, as well as their freestyle routine. On the second night, the couples performed a fusion dance of two previously learned dance styles. Couples are listed in the order they performed.
