there will be 18 housemates
in BB clue all HOH'S will be private so if you win HOH no one will know including your nominees but before the POV everyone can vote for who they think won HOH and if the majority get it right the HOH'S nominees will be safe and the HOH will be instantly evicted
so going for HOH is risky you could get someone you want out gone or end up getting the boot yourself
