On Day 1, fourteen HouseGuests entered the BBCAN Grand Hotel. They were then dealt their first twist. Two HouseGuests, Nick and Phil, were revealed to be brothers. The brothers will act as one HouseGuest, alternating who will participate in competitions each week. The brothers selected Nick to compete this week. They will be nominated and evicted together, and they will only have one eviction vote between them. If they make it to the end, they will split the prize money. Shortly before the Head of Household competition, the HouseGuests were asked to bet who they thought will be the first HouseGuest eliminated and the Head of Household. The HouseGuests selected Joel and Nick, respectively. If Joel defies expectations and is not the first one eliminated, he will win immunity for the week. If Nick does not live up to expectations and does not win Head of Household, he (and his brother Phil) will be locked away in isolation for the night. The HouseGuests then took part in the first Head of Household competition, One Night Stand. HouseGuests stood on a narrow beam while holding onto a rope. As the competition continues, the rope would wind towards the center, dragging the HouseGuests with it. HouseGuests must remain on the beam and keep the rope in their hands. The last HouseGuest standing on their beam with their rope in their hands will be the first Head of Household. Joel earned safety, Nick & Phil were both locked away in the High Roller room for the night. Loveita won the competition and became the first Head of Household of the season. A showmance started to blossom between Kelsey and Jared. Loveita hoped to split them up as they could be dangerous down the road. At the nomination ceremony, Loveita nominated Kelsey and Paige, with Kelsey as her target. Loveita, Kelsey, and Paige, as well as Sharry, Nick & Phil, and Raul, with Dallas as the host, competed in the What the Shell? Power of Veto competition. While dressed as mermaids, HouseGuests had to slide down their bumpy lane, grab a letter, and take it back to their puzzle board. Once they had all the letters, they had to solve a mystery phrase. The first HouseGuest to solve their puzzle will win the Power of Veto. Nick & Phil won the Power of Veto. At the Veto Meeting, the brothers decided to keep Loveita's nominations intact. Though the brothers kept the nominees the same for Loveita they rather keep Kelsey in the house over Paige for the fact if Kelsey and Jared are a showmance people would go after them. Along with their influence and Kelsey's campaign of flirting on Day 7, Paige was evicted by a vote of 7–4, receiving the votes of Dallas, Maddy, Ramsey, and Sharry. Shortly after Paige's eviction, Tim and Nikki were revealed to be the two wildcards and became HouseGuests. They received immunity for the upcoming week.
