Sometimes they're obvious, but game editor Wyna Liu knows how to trick you by using words that can fit into more than one group. Read on for today's Connections hints and answers.

How to play Connections

Playing is easy. Winning is hard. Look at the 16 words and mentally assign them to related groups of four. Click on the four words you think go together. The groups are coded by color, though you don't know what goes where until you see the answers. The yellow group is the easiest, then green, then blue, and purple is the toughest. Look at the words carefully and think about related terms. Sometimes the connection has to do with just a part of the word. Once, four words were grouped because each started with the name of a rock band, including "Rushmore" and "Journeyman."
