There may be an exception to this process or a "twist". Examples include: * New housemates who arrive sometime after Day 1 usually cannot make nominations or be nominated for eviction in their first week. * The housemates that will face eviction are decided by the success or failure of a task set by Big Brother. * A housemate is banned by Big Brother from making nominations one week for breaking rules, especially the rule regarding discussion of nominations. * A housemate is automatically nominated for eviction by Big Brother for rule breaking. * In the final week, no nominations are made and the public vote based on who is left.
