This is the 10th season of Survivor, this is the first time to have 20 castaways. But, after a problem with Survivor: Vanuatu, we have to continue the 18 castaways move. So there were no Tribes, so there is the indivilual immunity to make the first pick. Johnny & Damieta were not picked & sent home. Later the game offically began. No merge happened.
If there is a tie in the game, they are going to do a fire-making competition for the 2 castaways that got a tie. First one to make fire stays, the loser is voted out, which only happened in Carol & Bobby's only 2 castaways of Ulong. Also happened in Jen & Ian's tied vote of 2-2. At Episode 6 tribal council, Jacob & Abraham had a tie of 2-2. Instead of a fire-making compeititon, there was the tie-vote tribal council, only Bobby & Carol can only vote. Bobby still voted for Jacob. Before, Carol voted for Abraham, but later, at the tie-vote tribal coucil. She change her vote to Jacob, which made Jacob voted out.
