When? Guess the year

When? shows you one event from world history and asks for the year it happened. You get five tries. Each guess is rated exact, hot, warm, cold or ice cold, and the possible range narrows as you go. It is the daily puzzle on Mondays, Wednesdays and Fridays, and you can play it without limits in the Arcade. Every answer links to the full story of the event and a map of the world in that year.
