The last contestants try for riches Sunday at 9 on the finale of ABC's 14-night game show, "Who Wants to Be a Millionaire."

As he has for the past two weeks, host Regis Philbin reads multiple-choice questions of increasing difficulty. For each correct answer, prize money is doubled. After reaching the $1,000 or $32,000 level, contestants are guaranteed that amount, even if they miss future questions worth more. That may sound good, but after reaching the $500,000 point, the next wrong answer means losing $468,000. In Britain, where the game show originated, no one reportedly has gone for the entire 1 million pounds, settling instead for the half-million sum.

To determine the correct answer, contestants may ask the studio audience for advice, make one phone call for help or request that the on-screen display of four possible answers be reduced to two, one of which is correct.

If it does well, the quiz show could provide ABC with another low-cost prime-time series, following in the path of Drew Carey-hosted "Whose Line Is It Anyway?"
