In your skin_Arcade.php or skin_v3arcade.php file search for this (it's near the top)

function game($game,$top,$extra) {
global $ibforums;
return <<<EOF
	<!-- Add JS function for pnFlashGames Updated games component (Not Sure if this is needed yet) -->
	<script type="text/javascript">
	<!--
	function refreshScores()
	{
	}
	//-->
	</script>

Below that add

	<table width="75%" border="0" cellspacing="1" cellpadding="4" align="center">

  		YOUR ADSENSE CODE
