Big Brother 18 (US)

 is the current season of Big Brother (U.S.). It will last an American record 99 days.

Twists

 * Returning Players: Four fan-favorite HouseGuests returning from past seasons, Da'Vonne Rogers and James Huling from Big Brother 17, Nicole Franzel from Big Brother 16, and Frank Eudy from Big Brother 14 will return to compete against twelve new HouseGuests.
 * Teams: Similar to the Cliques from Big Brother 11 and the Coaches from Big Brother 14, each HouseGuest was placed on a team of four, with one returning HouseGuest on each team. Each week, the Head of Household's teammates are safe from eviction.
 * Day One Eviction: On Day 1, it was revealed that the loser of the final part of the Hit the Road competition - a member of the Freakazoids team - would be evicted if they came in last place. This HouseGuest ended up being Glenn Garcia, and he was the first HouseGuest evicted from Big Brother 18.
 * Roadkill Competition: Similar to the MVP twist from Big Brother 15, each week the HouseGuests will compete in the Roadkill Competition. The winner of this competition will be privately informed of their victory. This HouseGuest will receive the power to secretly name a third nominee for eviction, with no obligation to ever reveal his or her identity. If the "Roadkill Nominee" is taken off of the block due to the Power of Veto, the Roadkill winner will have to secretly name a replacement nominee.
 * Battle Back Competition: Similar to Survivor's Redemption Island, the first five evicted HouseGuests will compete against each other to re-enter the house. All four competitions will happen back-to-back. The first two evicted HouseGuests, Glenn Garcia and Jozea Flores, will face each other in the first competition. The winner of that competition will face Victor Arroyo, the third evicted HouseGuest, in the second competition. The winner of the second competition will face the fourth evicted HouseGuest in the third competition. Finally, the winner of the third competition will face the fifth evicted HouseGuest in the fourth and final competition, and the winner will re-enter the house.

Week 1
When the 12 new HouseGuests entered the house, they were informed that there would be three twists in the game. First, four former HouseGuests will be returning to the game (Nicole Franzel, Da'Vonne Rogers, Frank Eudy, and James Huling). Second, they will be divided into four teams of four. The teams were picked and named by the HouseGuests themselves. The four teams then began a competition with prizes and rewards, with the first place prize being immunity from the first two evictions. The winning team was Team Unicorn, consisting of James, Natalie Negrotti, Victor Arroyo, and Bronte D'Acquisto. Shortly after the competition, the HouseGuests were informed that one HouseGuest would be evicted before the two-night premiere concluded. Julie explained that the teams will compete in a three-part competition, and that the winning team in Part 1 would be granted immunity from the upcoming eviction, as well as the winning team from Part 2. The remaining team then must compete against each other in Part 3, and the HouseGuest that loses the final competition will be evicted. Category Four, consisting of Frank Eudy, Paulie Calafiore, Michelle Meyer, and Bridgette Dunning, won Part 1 and were safe from the next eviction. Part 2 was won by Team Big Sister, consisting of Da'Vonne Rogers, Jozea Flores, Zakiyah Everette, and Paul Abrahamian. In Part 3, Team Freakazoids, consisting of Nicole Franzel, Glenn Garcia, Corey Brooks, and Tiffany Rousso, faced off against each other. When Glenn failed to complete the competition in time, he became the first HouseGuest evicted from the house. As a part of the twist, the Head of Household for the week was to be one of the three surviving HouseGuests. Together, they chose Nicole as the first HOH of the summer. After hearing that he was targeting the veterans, Nicole decided to nominate Jozea as her target alongside Paulie, hoping to use Paulie as a pawn to send Jozea home. The next twist of the summer came into play with the BB Roadkill Competition. Frank was the winner of the competition and was given the power to anonymously nominate a third nominee. Frank decided to nominate Paul for eviction alongside Paulie and Jozea. At the Veto competition, the three nominees, Nicole, Da'Vonne, and Corey competed, and Paul won. At the Veto ceremony, Paul used the veto on himself and Bridgette was named as the replacement Roadkill nominee. At the eviction, Jozea was evicted by a vote of 7–4–0.

Week 2
Following Jozea's eviction, the remaining HouseGuests competed in the Head of Household competition. Paulie was crowned the new HOH, so he and the rest of his team were immune from the next eviction. At the nomination ceremony, Paulie decided to nominate Paul and Bronte with hopes to fulfill a plan to backdoor Victor. Victor ended up winning the Roadkill competition for the week and decided to nominate Tiffany as his target. The other HouseGuests continued to play Victor, as he remained the house's target even though he was convinced that it was Tiffany. At the Veto competition, Paulie won his second competition of the week and won the Golden Power of Veto. At the Veto ceremony, Paulie continued with his plan and used the Veto on Paul, putting Victor up in his place. At the eviction, Victor was evicted by a vote of 9–1–0, with Paul casting a sympathy vote against Bronte.

Week 3
Following Victor's eviction, the HouseGuests competed in the "Kiss My Ace" Head of Household competition in which Bridgette was crowned the new HOH for the week. Immediately, the other HouseGuests believed that Frank would be the one controlling Bridgette's nominations due to his close relationship with her. At the nomination ceremony, Bridgette went through with Frank's plan to get rid of his biggest threat, Tiffany, and nominated her and Paul for eviction. At the Roadkill competition, Frank won his second Roadkill of the summer and decided to nominate Bronte.

Notable Prizes

 * Week 1's first challenge gave out 2 prizes to the top placing teams, with the Freakazoids getting $10,000 to split evenly among the 4 teammates, and Team Unicorn getting immunity from the first 2 evictions.

Notable Punishments

 * Week 1's first challenge gave out 2 punishments to the lowest placing teams, with Big Sister becoming Have-Nots, and Category 4 given pixelated outfits (underwear for the men, bikini tops and bottoms for the women) to wear for the rest of the week.

Trivia

 * This season's opening sequence goes back to the older theme music last used in Big Brother 13, rather than the newer version released and used in Big Brother 16 and 17. Likely reverted due to throwback for the veterans.
 * However, from the episode with the first Veto competition, the music has changed back to the newer version for reasons unknown.
 * The reason for the change to the older music, and then back to the newer music are both currently unknown.
 * Ironically, Season 13 was the last season to bring back former HouseGuests that started off as HouseGuests rather than coaches. That season also had it's own Newbies vs Veterans alliance.
 * This is the first season to bring back past HouseGuests since Big Brother 14.
 * Coincidentally, in that season the HouseGuests started with 12 newbies and 4 vets that split up into teams based around the vets, just like this one.
 * This is also the first season since Big Brother 14 to evict a HouseGuest within the first 2 days.
 * 3 out of the 4 veterans (Frank, Nicole, and James) all earned 7th place in their seasons. Da'Vonne is the only one who didn't get 7th, instead getting 16th.
 * This is the first season with 2 HouseGuests of the same gender with extremely similar names, being Paul and Paulie.
 * When choosing teams, Da'Vonne mixed up the two and almost picked Paulie when she really wanted Paul. However it was all cleared up and Paul was on her team, with Paulie on Frank's team.
 * Da'Vonne was the first veteran HouseGuest to improve her placement, all by surviving the first eviction. She was also the only veteran not to win anything in Week 1, as James had immunity, Nicole was HoH, and Frank won the Roadkill.
 * This is the first season with 3 nominees on the block during eviction night since Big Brother 15.
 * Ironically, Season 15 is the only season of the 4 before this season to have no returning players.
 * This season also features two siblings of former houseguests Paulie Calafiore (brother of Cody Calafiore from Big Brother 16) and Tiffany Rousso (sister of Vanessa Rousso of Big Brother 17).
 * This is the second season where the first three evicted houseguests are male. The first season was Big Brother 15.
