It provides the rules of the game where students start with $3 and can win a $9 prize if the ball lands on numbers 1-12, but lose their $3 for other numbers. It notes the risk is 67% and return is a potential gain of $6 or loss of $3. Students are asked their preference to play the game, save their $3, or buy the product directly.
