Contemporaries

You are dealt a hand of historical figures with their birth and death years. A group counts only if a single year exists where every member was alive, that is, the latest birth is no later than the earliest death. Build the largest such overlapping group, faster for more points.

• Tap figures to add them to your set
• The overlap readout tells you whether everyone currently selected shares a year
• Use a hint to reveal a member of a largest possible group
• Submit your biggest valid group before the clock adds up

• Desktop: click figures to select them, click Submit, Clear or Hint
• Phone & tablet: tap figures and the action buttons

• Sort the overlap in your head by the latest birth and earliest death, those two dates set the window
• One long-lived figure can bridge two generations that otherwise never overlap
• Easy, Medium and Hard change the hand size and how tightly the lifespans cluster
