Big Brother: Over the Top premiered Sept. 28 on CBS All Access — the first in a string of original series set to debut on CBS' new streaming service in the coming months. During the premiere, it was revealed that Big Brother 17 alum Jason Roy would return to the Big Brother house as the 13th and final Houseguest for the new season, as determined by viewers' votes. Watch his introduction to the other contestants below.

That choice was one of many that will be offered to fans during the upcoming season. Mashable can exclusively reveal the four new ways viewers can impact the game over the course of the upcoming digital season, with voting open through the show's website.

For the first time in Big Brother history, fans will be able to watch every aspect of the season play out live via CBS All Access, including all the Head of Household (HOH) and Power of Veto competitions, as well as the weekly live evictions.

CBS All Access subscribers can vote in four different ways during Over the Top:

America’s Nominee Vote – The HOH will nominate two Houseguests for eviction and, for the first time ever, fans will have the opportunity to choose a third houseguest to join them on the block.

America’s Eviction Vote – In addition to the house’s eviction votes, for the first time, fans will have a say in who they would like to see go home. The nominee who receives the most eviction votes from America will receive one extra vote during the eviction ceremony.

America’s Care Package Vote – Fans can vote to send their favorite Houseguest a special advantage in the game.

America’s Have Nots Vote – America will be able to vote and choose three unlucky “have nots” each week.

This season's first Head Of Household competition will stream live on Thursday, Sept. 29 at 4 p.m. ET/1 p.m. PT on CBS All Access, with a "Weekday Replay" show streaming at 10 p.m. ET/7 p.m. PT. Big Brother: Over the Top will stream its first vote of the season on Sunday, Oct. 2 at 11 p.m. ET/8 p.m. PT., when it will debut America's Nominee Vote.

Big Brother: Over the Top is now streaming on CBS All Access. The broadcast iteration of the show will return in summer 2017.
