  If anyone knows if there's an explanation for this game anywhere on the internet please let me know. I was able to work through it but I really want to over it before the November LSAT because it was pretty tricky and similar to the type games that the powerscore guys predicted could be on this upcoming test

  Might be a while before the official video comes out but here are my notes for working out the game set efficiently. Let me know if this helps.

  F G H I Q R S V
  5/8 in, 3 out, conditional chains

  G -> F -> S/V
  H -> F

  V -> Q and R
  /Q or /R -> /V

  H -> /Q and /I -> /V

  G and S -> /I and F and /V

  key inference:
  S and V both out -> /F would force both GH out, insufficient remaining
  therefore at least one of S/V always in

  split three scenarios:

  in: S
  out: V
  remain: F G H I Q R

  in: V Q R
  out: S H
  remain: F G I

  in: S V Q R I
  out: F G H

  1. /I, MBF: SV triggers I in

  2. FH in, must be in?
     in: FHS
     out: QIV
     remain: GR, must fill in to FHSGR

  3. QV in, could be in?
     in: QVR
     out: H
     remain: F G I S

     a. SH violate V -> /H
     b. SI ok
     c. SF violate S/V
     d. GI violate G -> F
     e. GH violate V -> /H
     

  4. /Q, must be in?
     in: S
     out: Q V
     remain: F G H I R 4/5

  can I out? SFGHR ok. eliminate choices with I.

      a. SV no
      b. RS ok
      c. RV no
      d. HI, I out possible
      e. GI, I out possible
  
  no test method:
  

  S must be in, so eliminate CDE. V must be out, so eliminate A. B remains.

  Thanks so much for sharing your notes! Just had a quick question - how did you determine that SV triggers I in based on the third scenario? Idk if I got the contrapositive wrong while setting up my diagrams, but for the third diagram (S & V in) I got SVQR: in and HG: out with two remaining floaters F/I and I/F...thank you for clarifying!

  Wondering the same thing as @sk1491625. How did you determine that SV being in triggers I to be in as well?

  @sk144404, @kchrissy111

  If SV are both in or both out then you're failing the necessary condition in the final rule for F, i.e., "exactly one of S or V is selected," therefore FGH are out. If FGH are out then the entire out-group is filled meaning IQR have to be in.

  @claremont ahhhhh I forgot it said "exactly one", okay that makes a lot more sense. Thank you very much!
