this is a survival game. each member has 15 points each. just simply add one point to your bias then minus to your least bias.

example:
my bias is yoona and my least is sunny.

YOONA - 15
YURI - 15
TAEYEON - 15
SEOHYUN - 15
TIFFANY - 15
JESSICA - 15
SOOYOUNG - 15
SUNNY - 15
HYOYEON - 15

then it will become

YOONA - 16 (+)
YURI - 15
TAEYEON - 15
SEOHYUN - 15
TIFFANY - 15
JESSICA - 15
SOOYOUNG - 15
SUNNY - 14 (-)
HYOYEON - 15

when a member continous losing point until getting zero. out of the list! eliminated!

have fun guys. (nobashing)
