Big Brother Universe

Big Brother Universe is a game series hosted by Shattered. It is based on the U.S. reality TV show, Big Brother. A group of 13 to 18 contestants, known as "HouseGuests," compete to win the series by voting each other off and being the last HouseGuest remaining. One HouseGuest, known as the Head of Household (HoH), must nominate two of their fellow HouseGuests for Eviction. The winner of the Power of Veto (PoV) has the option to save one of the Nominees from Eviction, forcing the HoH to Nominate another HouseGuest in his or her place. The HouseGuests then vote to Evict one of the Nominees, and the HouseGuest with the most votes is Evicted. When only two HouseGuests remain, the most recently Evicted HouseGuests (generally 7 or 9) form The Jury and decide which of the two remaining HouseGuests would win the grand prize: a fictional $500,000.

Each season includes numerous modifications, or "twists", on the core rules in order to keep the players on their toes and to prevent players from relying on strategies that succeeded in prior seasons. The twists are typically adapted from various seasons of the Big Brother television show across the globe, with some kinks adjusted to fit the game's format. These twists have included cliques, split houses, dynamic duos, battle of the block, secret partners, perfect matches, special powers, multiple Nominees, public Eviction voting, and more.

The series takes its name from its incorporation of HouseGuests and twists from the various Big Brother television series across the globe. It has continued to be a hit for RTVG despite the cancellation of two seasons, and is the longest-running Big Brother Reality-Based Game to date.
