<p style="line-height:1.75;margin-bottom:30px;">In Task 1, you will play a number search game. There are two types of grids filled
with numbers: the 5*5 big grids and the 3*3 small grids, as shown below.</p>

<div style="display: flex; justify-content: space-between;">
    <div style="margin-left: 140px;">
        <p style="text-align:center;"><b>Big Grid</b></p>
        <canvas id="gridCanvas" width="300" height="300"></canvas>

    <div style="margin-right: 180px;">
        <p style="text-align:center;"><b>Small Grid</b></p>

<p style="line-height:1.75;margin-bottom:20px;">In Task 1, you will play a number search game. There are two types of grids filled
with numbers: the 5*5 big grids and the 3*3 small grids, as shown below.</p>

<p style="line-height:1.75;margin-bottom:20px;">The game has 10 rounds, each involving a number search task to earn tokens. In each round, <strong>the objective is to
    find a minimum of 3 pairs of numbers that add up to 100 in a grid within 45 seconds</strong>. To pin down each pair, you need to
    click on the two numbers that meets the requirement consecutively, so that the corresponding boxes will be labeled with a unique color.</p>

<p style="line-height:1.75;margin-bottom:20px;">Except the first round where you must work on a big grid,
    <strong>you are free to choose the type of grid you would like to work on in any subsequent rounds</strong>.
    Feedback will be provided at the end of each round.</p>

<p style="line-height:1.75;margin-bottom:25px;">To help you familiarize with the game to be performed, before round 1,
    you will be given a chance to practice on one small grid and one big grid. <u>While these practice exercises are not
    paid, they are there to help you become acquainted with the number search task, enabling you to perform better
        in the paid rounds.</u></p>

<div style="line-height:1.75;margin-bottom:20px;font-size:20px" align="center"> <strong>Your Earnings </strong></div>

<p style="line-height:1.15;margin-bottom:15px;">&#x2022 If you succeed in finding enough pairs in a big grid, you will earn 4 tokens. </p>
<p style="line-height:1.15;margin-bottom:15px;">&#x2022 If you succeed in finding enough pairs in a small grid, you will earn 1 token. </p>
<p style="line-height:1.15;margin-bottom:25px;">&#x2022 No token will be provided if you fail to find enough pairs within the given time constraint. </p>

<p style="line-height:1.75;margin-bottom:25px;">Your total earnings in Task 1 will be the tokens you accumulate across 10 rounds</p>
