The score ranking shows, for each registered player, the average of their results as a percentage and the number of quizzes played. You can limit it to one theme to see who does best in history, science or geography.
The weekly league adds up the Elo points won or lost during the current week. It starts again from zero on the date shown on the page, and the winner of the previous week is displayed there.
The Elo ranking measures progress: the score goes up when you answer a hard question correctly and goes down after a mistake on an easy question. It changes in Endless, in quizzes and in the daily challenge for signed-in players.
The Ascension ranking gathers the best ascensions of the week and of all time: the higher you climb through the fifteen steps and the more points you cash in, the higher you rise in the table.
