An advergame is a computer game made to advertise a product — a snack, a film, a brand. The game itself is the advertisement, or is built around it. The word is a blend of advertisement and game, and it is a marketing word, more at home in business articles than in the playground. Though actually, people stretch it. A regular game that merely shows ads while you play is not quite the same thing; that is a game with advertising in it. An advergame is closer to a game that exists so you will remember the brand. You may also see advergaming for the practice of using such games. The idea is not new — companies have made branded games for years — but the blend is.
