Tribe: 20 Tree Chop
Each tribe must have at least 2 active members for this challenge. In this challenge, you have a axe, and you are trying to get the tree to fall when the other tribe is chopping it. The tree takes 20 hits to fall. You can chop the tree either 1/2/3 times when you have the axe. So for example, if Person A and B is from Tribe X, and Person C and D is from Tribe Y, Person A might say 1,2,3 (Which shows that A has chopped the tree three times), then Person C might say 4,5 (Which shows that C has chopped the tree two times), then Person B might say 6 (Which shows that B has chopped the tree once), then D say 7,8 (Which shows it was chopped twice). They continue on alternating between the two tribes until the person that chops it the 20th time is eliminated from the challenge, and it continues until the tribe of the Sole Survivor wins the challenge.
EG- Person A and B is in Tribe X, Person C and D is in Tribe Y
Person A: 1,2,3
Person C: 4,5
Person B: 6
Person D: 7,8
Back to Person A: 9
Person C: 10, 11, 12
Person B: 13, 14
Person D: 15, 16, 17
Back to Person A: 18, 19
Person B: 20
And then Person B is out of the game.
Tribe Y is down to one, and Tribe X is up by one.
You can do it with more people.
In the example, Person D will be the only left, but if he manages to get Person A and B out, Tribe Y will win the challenge.
