How it works

Every level has a clear goal: a set number of right answers clears it. A wrong answer costs you in the game and then shows you the right one. Play with arrow keys or W A S D, swipe, or tap the on-screen buttons. Music and sound effects each have their own switch, and you can pause any time.

Every fact in this game was checked against a cited source by a separate fact-checker. No ads, no coins, nothing to buy.
