Bayon wins IC
Shirin out


  • Ep2 Reward/Immunity challenge: "Yank Yer Hank" - Wholesale swapping out on the puzzle leads to a not-quite-right Ta Keo attempt, followed by another Bayon win.
  • Ep2 voted out: Shirin, 5-4 over Spencer.


Episode 2 scoring notes

Notes: Only one challenge, Ciera sits out.


  • Ta Keo try
  • Bayon's win

Was the final puzzle fair, though? We think the challenge department made a blunder here, in choosing a puzzle design with bilateral symmetry. Ta Keo's solution looks fine, except that it's wrong. This is due to two things: (1) having a design that mirrors itself across the midline, and (2) the logistics of having the puzzle look the same from the front and back (to make filming easier). That creates Ta Keo's situation in which the left half, when reversed, is exactly the same as the right half. Because the contestants are not shown the solution before they do the puzzle, they have no idea whether it's symmetrical or a repeat of the same image. The only clue Probst gave was that "the design flows."


option 3Here's the problem, though: The solution doesn't actually do that. There is nothing in the correct design connecting the two halves across the middle. Clearly, Bayon's solution is better, because Ta Keo's has a branch in the middle that ends in mid-air. But it's hard to claim Bayon's is the only possible solution. What if Ta Keo had inverted the symmetry, and had the branches run into each other in the middle (shown below). Would that have been wrong, too? Because based on Probst's clues, it's more right.


Make better puzzles, Survivor.

Glossary of terms
  • Challenge stats
    • ChW: Challenge Wins. For tribal challenges, a contestant earns a fraction of 1 win, depending on if they participated (no points for sitting out). So in a five-person tribe's win, each participant gets (1/5) of a point, or 0.2 points. Duels (or individual RCs as in Ep1) at Redemption Island count as half a challenge (and half a win). Individual challenge wins count as a full point.
    • ChA: Challenge Appearances. Used to calculate ChW%. Fractional for tribal challenges (same as ChW), except sit-outs get charged for an appearance, because they could have participated.
    • ChW%: Challenge Win%. Simply, ChW% = ChW / ChA.
    • SO: The number of times a contestant sat out of a challenge.
    • Plc: Place finished in an individual challenge
    • %Fin: Percent finish - roughly, percent of a win achieved, with 1 being 100%.
    • MPF: Mean % finish - mean of all % finishes in individual challenges.
  • Tribal Council stats
    • VFB: Votes For Bootee. The number of times the contestant has voted for the person who was ultimately voted out. Applies only to initial votes (no points for revotes in case of a tie). Special case: In a final three TC, where only one vote is cast (by the F3 IC winner), only that vote counts.
    • VAP: Votes Against the Player. The total number of tribal council votes cast against the contestant. Again, only initial votes count (no penalty for revotes), and here a hidden immunity idol (if played) erases the votes. In the special case of a final three tribal council above, only the F3 bootee receives a vote against.
    • TotV: Total votes cast during the tribal councils the player has attended (again, only initial votes count). Used to adjust for different vote totals as tribes shrink.
    • TCA: Tribal council appearances. The number of times a contestant has attended tribal council (at which they voted).
    • TC%: Tribal Council percent. Attempts to reward voting for the bootee (which players controlling the vote almost always do), while punishing receiving votes yourself. The formula is: TC% = [VFB - (VAP/TotV)] / TCA.
    • wTCR: weighted Tribal Council Ratio. Very similar in intent to TC%, but calculated as a ratio of VFB to VAP, while also scaling to a uniform number of TC appearances. The formula is as follows: wTCR =2* [VFB / (4+VAP)] x (14/TCA). I originally tried (1+VAP) to avoid dividing by zero, but this overly rewarded getting zero votes against relative to just one vote against, which seemed silly. (4+VAP) scaled that effect back comfortably. 14 was used as the scaling factor for TC appearances because there are usually 14 episodes, then a final scaling factor of 2 to bring maximal scores up to roughly even with ChW and JV% high scores.
  • Jury stats
    • JVF: Number of jury votes for the contestant to win. Maximum nine (Earl Cole, Fiji), theoretically.
    • TotJ: Total number of jurors. Necessary to not punish unanimous 7-juror winners (JT Thomas, Tocantins).
    • JV%: The percent of total jury votes cast for the contestant, or Jur% = JVF/ TotJ. This number is used, raw, in SurvSc, and is scaled in SurvAv (multiplied by six) to make it similar in size to ChW and wTCR.
  • Overall scores
    • Survival Score (SurvSc). It's simply the sum of Challenge Win% (ChW%) + Tribal Council% (TC%) + Jury Vote%, for a maximum possible score of 2 (3 after the finale).
    • Survival Average (SurvAv). It's a simple sum of fractional Challenge Wins (ChW), weighted TC Ratio (wTCR), and (eventually) a weighted Jury%. The latter two max out at six points total, for a theoretical maximum score of around 18 or so.
