Simple...majority rules.
Each round you all vote 1 person out...person with most votes goes.
In the even of a tie, a tiebreaker challenge is set.

IMMUNITY: As the prize at the end is 8T$, there are 8 immunity passes available.
To use an immunity pass, simple add the word IMMUNITY in your Vote PM.
You may use immunity as many times as you want, but there are only 8 immunity passes in the whole game.
