Replace doomscrolling with learning. Each day, Spark explores a single theme through thoughtful puzzles spanning ancient history, mythology, movies, food, geography, and more.

With five unique games and new puzzles every day, Spark makes learning part of your routine. Each game offers a different way to explore the day's theme, and each one teaches you as you play.
 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
 All of Spark's puzzles are crafted by experts, not AI, and designed to spark those "aha" moments that make ideas stick. Explore hundreds of topics in the Library, from ancient history to the animal kingdom, with past themes to revisit anytime. Along the way, you'll uncover facts that are fun to learn and even better to share.
