WARM up those fingers, ABC opened the phone lines for wannabe contestants to qualify for “Super Millionaire” last night.

The weeklong super-sized version of “Who Wants to be a Millionaire” kicks off on Feb. 22 with a $10 million prize – 10 times more than the original $1 million haul.

To become a contestant, candidates can call in and try to correctly answer five general knowledge questions by putting the answers in correct order, similar to the show’s “fastest-finger” round.

The phone line – 1-800-999-7878 – is open from 7 p.m. to 3 a.m. until February 24, ABC officials said.

No former hot-seat contestants from older editions of “Millionaire” are eligible to play.
