About This Test
Four geniuses who can explain the universe but not a party invitation — and the neighbor who translates. The Big Bang Theory's faces are sitcom canon: Sheldon's smug certainty, Leonard's hopeful resignation, Howard's misplaced confidence, Raj's sweet silence, Penny's amused patience. Bazinga included.

Featured Characters
These are the characters you can be matched with.

An experimental physicist with a genius IQ and a lactose problem, who spent years proving the girl next door was not out of his league. The most normal one in the apartment — which says everything.

A theoretical physicist with two doctorates, one designated couch spot, and zero understanding of sarcasm. Knocks three times, drinks tea when upset, and is always right — just ask him. Bazinga.

The aspiring actress across the hall who wandered into nerd territory for pasta and stayed for a decade. No PhD, yet outsmarts four geniuses weekly with pure street sense.

The aerospace engineer who went to actual space and still lives with his mother. Retired his creepy pickup lines when he met a tiny blonde microbiologist who terrifies him — in a good way.

The astrophysicist who literally couldn't speak to women without alcohol for six seasons. Sensitive, dramatic, owns a tiny dog named Cinnamon, and throws the group's fanciest dinner parties.

A microbiologist with a cartoon-sweet voice that drops an octave when she's angry — and everyone runs. Out-earns her astronaut husband and rules the group with adorable menace.

A neurobiologist who spent years dissecting brains before discovering friendship, fashion — by her standards — and one very structured romance. Wrote a relationship agreement and loves it.

The comic book store owner whose self-esteem is lower than his profit margin. Art school graduate, chronically pale, and delivers the saddest one-liners with a smile.

The dermatologist girlfriend with a taste for horror movies and slightly alarming hobbies. Sweet smile, scalpel steady — the guys never quite figured out if they should be scared.

The brilliant lawyer little sister who flew in from India and immediately destabilized the entire friend group. Argues circles around everyone — including her brother's best friend's girlfriend.
