OneAcross is built on the puzzle-solving technology originally developed by a team of computer scientists at Duke University. After creating a computer program capable of solving tough American-style crossword puzzles, several of the researchers created the OneAcross site. The main function of the site is the crossword clue search, designed to help human solvers when they are stuck on a puzzle.
The system accepts crossword clues and answer patterns (Serpent) and quickly returns a scored list of suggestions ("gartersnake", "rattlesnake"). It can help on ambigious clues (Greenish blue: "teal", "aqua", "cyan", "nile") as well as highly specific ones (Designer Schiaparelli: "elsa"). Over the past two years, OneAcross has added other puzzle solving technologies to the site, including help for anagrams and cryptograms, in addition to a simple dictionary lookup.
