Did You Know?
About PlayMemorize Did You Know?
Did You Know? is a cloze-fact streak game. A fact is displayed with one key word blanked out, and you pick the correct word from a short list. Get it right and the next fact appears; miss once and the streak ends.
Three fact flavours. Useful facts · practical knowledge worth remembering (unit conversions, record holders, scientific definitions). Fun facts · surprising and counterintuitive trivia. How it works · short mechanical explanations of everyday phenomena.
Same engine as Useful Fact and Fun Fact. Did You Know? bundles all three flavour pools in one place and lets you filter by topic or mix them. The round engine is the shared cloze-fact format already used across the PlayMemorize catalogue.
All 25 languages. Every fact is translated into the full PlayMemorize locale set, so a French player reads French facts with French answer choices.
Part of the PlayMemorize family of brain-training games. Runs entirely in your browser, works offline as a Progressive Web App.
