The 24 Game was invented in 1988 by American mathematician and educator Robert Sun, who wanted students to practice mental math in a fun, competitive way.
It spread quickly through schools in the United States and later across Asia and Europe — especially where mental arithmetic is celebrated. Tournaments, timed decks, and classroom editions made “making 24” a shared language for logic lovers.
24MathGames carries that spirit into a modern app: the same “aha!” moment when the four tiles finally click, wrapped in a calm, premium interface for phones and tablets.
Glass-smooth UI on iPhone and iPad — the same calm brilliance you get in the app.
