Big Brother 18 (U.S.) Voting Chart

Notes
 * 1) As Victor was the last HouseGuest standing in the opening competition, Team Unicorn won immunity from the first two evictions.
 * 2) After Team Unicorn won immunity from the first competition, the members of the other three teams competed in a three-round competition, with the losing HouseGuest after the third becoming evicted. Teams competed in the first two rounds; Category 4 and Big Sister won, earning safety. The remaining team, Freakazoids, competed in the third round individually. Glenn lost the competition and became automatically evicted. The team then had to choose one of their remaining teammates to become the first Head of Household; they chose Nicole.
 * 3) During the team phase of the game, the Head of Household's teammates earned immunity from eviction for the week. The team phase ended after week 4.
 * 4) The winner of the Roadkill competition earned the power to nominate one HouseGuest for eviction. The Roadkill competition winner makes their nomination privately, and the HouseGuest is not obligated to reveal their identity. If the veto is used to save the Roadkill-nominated HouseGuest, the Roadkill winner also privately nominates the replacement. Their nominations become shown in bold. The final Roadkill competition was in week 4.
 * 5) Instead of permanent eviction, the first five evicted HouseGuests received a chance to return to the game through the "Battle Back" competition. The first two evictees faced off in a duel, in which the winner advanced to face the next evicted HouseGuest, and the loser became permanently eliminated; following four duels, Victor was the last evictee standing and re-entered the house on Day 37.
 * 6) For winning the "Eliminate Two Eviction Votes" Care Package, James was awarded the power to block two HouseGuests from voting in that week's eviction; he chose Corey and Paul.
 * 7) This week was a double eviction week. Following the first eviction, the remaining HouseGuests played a week's worth of games—including HoH and Veto competitions and Nomination, Veto and Eviction ceremonies—during the remainder of the live show, culminating in a second eviction for the week.
 * 8) For winning the "Super Safety" Care Package, Nicole was awarded immunity for the week.
 * 9) For winning the "Co-HoH" Care Package, Michelle was named Co-Head of Household, earning the right to make one of the nominations and replacement, if necessary. Michelle's nominations are shown in bold.
 * 10) During the Head of Household competition in Week 10, the first five jurors — Da'Vonne, Zakiyah, Bridgette, Paulie, and Victor — competed for an opportunity to come back into the game. The juror who lasted the longest would return to the game to win and be eligible to become Head of Household if that juror finished first amongst the other HouseGuests in the competition. Victor outlasted the other jurors and re-entered the house.
 * 11) For winning the "BB Bribe" Care Package, Corey earned $5000 to give to another HouseGuest; accepting the bribe would force that HouseGuest into completing the task. Corey bribed Victor in exchange for voting against Michelle.
 * 12) As Head of Household, Nicole was forced to break the tie on Day 79.
 * 13) During the finale, the jury members voted for which finalist should win Big Brother.
