Conetst Winner based on?

So hello there, I am kind of new to this website i entered this contest : https://www.designco...n/singlesource/
The contest is "Expired" right now.
so how is the winner picked, is the contest holder/ Client/ Business man (in this case SingleSource) the one who picks the winner? and what happens if he did not pick a winner? Does it go by the number of upvotes/likes or how does it go?

Clients select the winner. Also, client can request a refund if it is not guaranteed contest.

If it is guaranteed and client doesn't come back in a certain period (approx more than 3 moths), the contest goes to Designer's voting poll. 

Another thing... client can extend the contest if he/she had not been satisfy with designs or with number of participation of designers, or need more time to work on revisions. 

Thank you for the Explaination Moderator, but what if it is not guaranteed what does happen then? There may be no winner? and the money does not go to anyone?

Well, that may happen if not guaranteed. If client is not satisfied with participation or doesn't like any proposal. 

Regarding this contest, I think that many of you did not even read the brief or understand the task, which is disappointing. 

Yes I noticed as well the random entries

Thank you again for clarifying

You are welcome.
