Fifteen spellers have advanced to the primetime finals of the Scripps National Spelling Bee, where they'll test their knowledge of Webster's Unabridged dictionary.

Scripps usually takes about 10 spellers to the final rounds, but the competition was paused with 15 kids left after more than four grueling hours on stage Thursday.

At stake is a trophy and more than $40,000 in cash and prizes. After three consecutive years of ties, the bee is trying to identify a sole champion this year by adding a tiebreaker test.

Among the finalists is Tejas Muthusamy of Glen Allen, Virginia, who had two previous top-10 finishes. Three other former top-10 spellers were eliminated.
