Swipe before the fact
hits the floor.
FactFall isn't a slow, take-turns quiz. A fact card drops from the top and you've got seconds to call it — swipe right for TRUE, left for FALSE. Nail it and the next card falls faster. Miss it and you learn something new.

Miss a card and a candy-bright "Today I Learned" card flips over with the real answer and a one-line explainer — so you walk away a little smarter every time.
