Seek and find games are adventure games with graphics exception. In general, there is a storylineg. An old house full of object you have to search, a potentially haunted mansion, an Egyptian souk or a boat at the dock can be the scene of hidden object games.
As their name suggests, these are games in which various objects are mixed (and hidden). You'll have to seek and find all the objects that you request. Generally, they are included in a list and are striked progressively as you find them. When you are stuck, you have clues to help you.
