In 1988, Robert Sun created the first edition of the 24 GAME, Single Digits, to help train young minds in the processes and patterns of mathematics. Sun’s revolutionary approach alleviates a classic brand of math anxiety—getting the right answer—and instead puts emphasis on the method behind the math. Without fear, children naturally take action, explore, think mathematically, learn, grow and build a love for math that lasts a lifetime.

The 24 Game lineup quickly expanded from one edition to nine, and a grassroots marketing strategy known as the 24 Challenge Math Program provided games to U.S. classrooms, where their universal appeal to students from diverse economic and social backgrounds made them an instant success. These tournament-style events continue to excite schools and activate entire communities today.
