Common collocations

Originally popularized in the context of video games (cheat codes, hidden features, Easter eggs), the word has expanded to mean any clever insider tip. It is very common in lifestyle media, cooking shows, and online content, where it is essentially equivalent to the English "life hack." The tone is informal and positive — a 裏技(うらわざ) is a welcome shortcut, not something underhanded.
