What is Did You Know?

A cloze-fact streak game. A fact is shown with one word blanked out; you choose the correct word from a list. One wrong answer ends the streak.

What are the three topic types?

Useful facts (practical knowledge), Fun facts (surprising trivia), and How it works (everyday mechanical explanations). You can filter to one type or mix all three.

How is this different from Useful Fact and Fun Fact?

Did You Know? bundles all three flavour pools in one place with a topic filter. Useful Fact and Fun Fact each focus on one pool only; this game gives you all three and lets you switch.

Is it available in my language?

Yes · all 25 PlayMemorize languages are supported. Facts and answer choices are translated for every locale.
