The Top 24 contestants were announced on 19-20 April 2021. The Second Chance Challenge returned as Second Chance Week, with two eliminated contestants being given the chance to return instead of one. In addition to being exempt from the first Elimination Challenge, the holders of the Immunity Pins were able to use them at any point during future Elimination Challenges, including right up to the end of a challenge. Only three Immunity Pins were up for grabs this season, which all 24 contestants competed for during the first Mystery Box challenge.
