Each clip is a home video almost nobody has watched. Guess the year it was uploaded to YouTube.
Five clips a game. The right year is worth 1,000 points, and each year off costs 150. The month is an optional bonus: +100 if it's right, +50 if you're one off, and +500 if you get the year and the month exactly, a bullseye. You can skip two clips a round.
Things to go on: picture quality, the phones, cars and clothes in shot, and the file name, which can hint at the camera.
