Shelf Life

Five photographs of real consumer products, from chocolate bars to early computers and handheld consoles, are shown each day, and for each one the player estimates the year it first reached store shelves. Everyone gets the same five items, and results can be shared as a spoiler-free receipt. Stats and streaks stay in the browser.
