In World Detective, students select a continent and the "game" selects a secret country within the chosen continent. The player has six questions to try to guess the selected state. Users must generate "good" questions that allow them to eliminate as many incorrect states as they can per question. Students can ask questions regarding color or relative location. States that are eliminated are grayed out. For example, a good first question might be "is the country east of Germany?" If the answer were to be yes, all of the countries west of Germany would then be greyed out.
