Erebus: daily memory trivia

About Erebus

Erebus is a free daily trivia game built around one problem: you remember the story behind a fact, but not the name, date or place you actually needed. Every fact comes with a short, vivid scene and a memory hook for the hard word, so it has something to hang on to.

Each day you first try to recall facts you learned on earlier days, then learn a few new ones. Facts you remember easily come back less often, after a few days, then weeks. Facts you miss come back tomorrow. It takes about five minutes a day.

There are two daily lessons: general trivia (history, science, space, nature, film, music, art, literature, mythology, sport, food and more) and geography, which works through every country in the world by region: its capital, flag and where it sits on the map. There's also a daily challenge, the same six questions for everyone, plus unlimited map and flag practice.

You can read every fact and its memory story in the fact library, or read more about the method in how it works.
