Loot JewelryLogo Design Contest

Am I supposed to rank all variations of same logo?

I think you don't need to do that :)

Hello! Here are some hints for getting the most out of your contest as it progresses:

~~ Rank designs daily -- this will encourage participation.
~~ Rank a variety of designs to get a variety of entries.
~~ Ranking gets your contest noticed! Unless your contest is Private, 1st place entries are posted to the portfolio page: https://logotournament.com/portfolio
~~ When you provide feedback to designers, you increase the chances of getting the logo you want. More feedback = better results!
~~ Leave private feedback by clicking on a design. Feedback will be made public upon contest completion.
~~ Please note: if you are asking for a design that will require several hours to create, to attract designers willing to invest that amount of time the prize should be at least $400-$500. All "Character" style logos fall into this category.
~~ Designers are not offended by "Not Interested." We'd like to know what you don't want so we can give you the design you do want.
~~ Designers earn points for designs ranked 1st - 10th. We like to earn points.
~~ The first phase of the contest is the "Open" phase, and everyone can submit during that time.
~~ After your contest's initial "Open" phase closes, it will enter the "Top 5" phase; only the top 5 ranked designers will be able to submit revisions at that time.
~~ The "Top 5" designers are the first 5 designers in a contest, not the first 5 designs.
~~ When "Top 5" ends, the "Judging" phase begins. The designer of the 1st place design will be the only designer who can submit revisions at that time.
