 Spark's games include: This or That: Choose between two options to learn more about the day's theme Links: Find the common thread connecting people, places, and ideas Chrono: Put events in order to see how history really unfolded Knockout: Uncover surprising comparisons in a series of fun head-to-head matchups Hindsight: Pinpoint when and where a photo was taken to uncover the story behind it
