How To Play Breadcrumbs - the Guessing Game of 5 Crumby Clues

About Breadcrumbs, from BoardGameGeek:

In Breadcrumbs, one player lays a trail of subtle clues leading to a secret phrase, but they don't want everyone to get it right. The cluegiver reveals up to five clues, one at a time, trying to guide exactly the right number of players to the answer. Guessers can only guess once, scoring more points the earlier they get it right. The challenge is in giving clues that are clever, tempting and just vague enough. Make the trail too obvious and too many people will follow it. Make it too obscure and no one will get there. -description from the publisher
