The game
Which one started first?
Two products from the catalog. Pick the older. Keep going until you are wrong.
How it works
Every pair is drawn from the 110 products in the catalog that are still running, and the date behind each card is the founding date from that product's written entry, not a launch on Product Hunt or a first commit. Pick the one that started first. A right answer keeps the streak going; a wrong one ends the run and shows both dates.
The same dates drive the full ranking, the head-to-head comparisons, and the Daily Five, so a streak here is a fair test of how well you know when things began. If a date looks wrong, the product page has the reasoning and a way to send a correction.
