				<p>You will play a browser-based card game with some (friendly) monsters. The study will last
					approximately 20 minutes. You will be paid a compensation of 2.00$ for your participation and can
					earn a performance-based bonus.<br />
					<br />
					Please note that we can only pay you if you complete the study and if you read everything
					carefully. We will ask you to answer some simple questions about the instructions, which you need
					to answer correctly in order to participate and be paid.</p>
				&nbsp;

				<p>At the end of the game, you will receive a code to paste into the box below to receive credit for
					participating.</p>
				&nbsp;

				<p><strong>Make sure to leave this window open as you complete the game. </strong> When you are
					finished, you will return to this page to paste the code into the box.</p>
