A hidden object game (sometimes called hidden picture or seek-and-find) is a genre of puzzle video games where the player generally must find items from a word list that are hidden within a picture scene. Hidden object games are a popular trend in casual gaming, and are comparatively inexpensive to buy. Time-limited trial versions of these games are usually available for download.
Very often, these games are published as a standard edition (SE) and/or a Collector's Edition (CE). This trend has started since the release of Mystery Case Files: Dire Grove in 2009 has continued ever since. Collector Editions have extra content not found in Standard Editions, including but not limited to:
