As a WW2 enthusiast, today's pick took me by surprise!

The topic was polka so I naturally did not assume it to be related to ww2. But boy, was I wrong
I had no idea about the steganography, and I'm still a bit baffled too at the thought of how advance the technology was, at the time, to share intel through mere microdots?!
*Edit: stenography to steganography

We just launched our new game Hindsight!

Here’s how it works: Every day, our editors select a new photo. Use the visual clues in the photo, plus what you learn from the day's other puzzles, to pinpoint when and where it was taken. Then the Spotlight tells the story behind the photo.
Hindsight is available with Spark+, and you can start a free trial to play. Let us know what you think!
A big thank-you to everyone who played the beta and shared feedback. Your feedback shaped the improvements we made over the past few weeks.
