There's a U.S. and a World edition each day. You have 15 seconds per photo and four names to choose from; a right answer within a second scores 100, dropping to 10 at the buzzer. If a photo is hard to make out, you can swap it once for a small penalty.
The squares in a shared result show each round: green for 70 points or more, yellow for 40 or more, orange for any points, and red for a miss.
