Each day Yearline gives you 5 famous events, from inventions and world history to pop culture. Drag down through the century layers (or use the −10, −1, +1 and +10 buttons) to the year you think each event happened, then lock it in to see the real year and a short fact.
Exact or 1 year off scores 100 points; every extra year off costs 2 points. The best possible score is 500. A new set of 5 arrives every day at midnight in your local time.
