How your rating works
- Each game has its own rating. As it climbs the questions get harder, and if it drops they get easier, so they always suit you.
- Right answers raise your rating and wrong ones lower it. There is no rush: only a very slow answer counts a little less.
- Playing more rounds does not raise it by itself. Only playing better does, and a weaker round can lower it.
- Everyone starts at the bottom, Explorer I. Your rating moves after every answer, so the next question already fits you. It moves fast in your first rounds of a game and settles as you play more.
- It updates the moment a round ends. As a guest it is saved on this device only, so sign in to see it on the leaderboard.
