penalty specified in the rules. If the correct answer is selected, points are added to the total score. If the "pass" button or a wrong answer is clicked, the correct answer is displayed before the quiz continues. The game ends when either the timer reaches zero or the student has attempted to answer the maximum allowed number of questions (currently five of nine). At this point, all interactive features are disabled, the final score is computed and displayed, and the result is written into a file (linked to the student's username). Supporting materials contain a modified, online version of two such quiz games.
