This Head of Household competition is called “On the Mark” and here’s how it works:

In this competition, you have a tally board in front of you. Starting at 7pm EST, you can send a mail stating ‘*adds tally*. Then, when an hour has passed since your last mail, you can add another, and so forth.

The houseguest with the most tallies after 22 hours, at 5pm EST tomorrow, meaning your maximum possible score is 23, will become the new Head of Household.

Should there be a TIE, the winner will be the houseguest who mailed their final tally first out of those in the tie.

Power of Veto competition will be tomorrow at 7pm EST, so the Head of Household has just an hour for nominations.
