We both like Tiffany Blue. We both really love giraffes.

Like it's, like the randomest things.

Saint Mary's college roommates Samantha Carnero and Samantha Richards joke that they're so much alike, they're almost twins.

There is like a big joke because both of our names are Sam, obviously.

The pair was more than 80 % compatible according to StarRez, an online tool that more than 400 institutions, including Ohio State, NYU and UC Berkeley use to match roommates and organize on-campus housing.

It works like an online dating site, with a proprietary matching algorithm.

Fill out a questionnaire, find compatible matches and then check out profiles.

Attributes might include whether they smoke, you know, watch TV when, when they 're studying.

Do they like to cook?

Schools can decide which attributes to prioritize.

But Saint Mary's, with an undergraduate population of only 3, 000 students has kept the algorithms as broad as possible and focused on lifestyle choices.

Lindwall says StarRez has found that study and sleeping habits are often the two most important factors.

The combination of those two things can really, really say a lot about how a student relationship is going to go.

But StarRez is just the starting point for future roommates.

They're able to use Facebook or social media outlets to connect with that person and kind of get to know them on a deeper level.

StarRez says some participating schools have reported fewer room swap requests and roommate conflicts.

Saint Mary's says last year seven percent of first-year residents who were dissatisfied with their housing assignments requested a change.

Saint Mary's is hoping to see a decrease in the second year of using StarRez.

It 's working for freshmen Cameron Wiggans and Steven Hasbrooke.

They 've requested to live together again their sophomore year.

It makes college a lot easier.

We're actually 100 % compatible.

StarRez has a compatibility meter and we're 100 %.

Earning them an A in roommate matching.
