A past Centumth puzzle. Play it on this page with five guesses, or read the full Top 100 ranking below.

From monumental triumphs to world-changing tragedies, guess the most famous and widely recognized historical events of all time. (A special thanks to community member Evan Paquet for suggesting this topic!)

This list was researched and ranked by hand for Centumth. Entries near #1 are the names almost everyone thinks of first. Entries near #100 are true, a little obscure, and still fair if you think sideways. Sources below are the starting point — the final order can include small editorial calls so the daily puzzle stays balanced.

You can play this archive puzzle with five guesses, or reveal the complete ranking if you came here looking for the list. Revealing locks this puzzle — you won’t be able to play it afterward.
