The games about the U.S. government have generated a significant following. Fifty-seven percent of students who played Do I Have a Right?—one of the first free Web games iCivics released last year in the classroom went on to play it, unprompted, at home. In addition, 550,000 unique players have played the three judicial branch games featured on Ourcourts.org more than 700,000 times, per iCivics.
