I built Factle around one irritating idea: every puzzle hides an interesting fact or useful life hack, but you can’t read it until you uncover every word.

Choose your challenge: Easy: 3 hidden words Medium: 5 hidden words Hard: 7 hidden words

Stop one word short and the answer stays locked. Finish the grid and discover what the words were leading you towards.

Factle is available now on iOS, with Android currently in development:

Don’t download it just to be supportive. Try it to see whether the hidden payoff is actually strong enough to keep you searching—then tell me where the idea succeeds or fails.
