        For each of the rows below, please click on the lottery you prefer (A or B).
        <br><br>
        You will only be able to go to the next page once a lottery has been clicked for <span style="font-size:20px"><u><strong>each row</strong></u></span>.
        <br><br>
        On the next page, one of your choices will be randomly picked and played.
        <br><br><br>
        <strong>Example of how to read the lotteries:</strong> In row #1, if you choose Lottery A, and the dice number is 1, your payment will be 550 points. However, if the dice number is anything from 2 to 10, your payment will be, instead, 450 points. Alternatively, if you choose Lottery B in row #1, your payment will be 750 points if the dice number is 1, and 250 if the number is anything between 2 and 10.
