To get the boarder replace all the template code in adv_portal_rand_arcade with this:
Code:
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="$stylevar[tablewidth]" align="center">
<thead>
<tr>
<td class="tcat" colspan="2"> <span class="smallfont"><strong>$vba_options[portal_blockbullet]
<a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumhome_randomtopic')"><img id="collapseimg_forumhome_randomtopic" src="$stylevar[imgdir_button]/collapse_tcat$vbcollapse[collapseimg_forumhome_randomtopic].gif" alt="" border="0" /></a>
<a href="$vboptions[bburl]/arcade.php?$session[sessionurl]"> Arcade Game</a>
</td>
</tr>
</thead>
<tbody id="collapseobj_forumhome_randomtopic" style="$vbcollapse[collapseobj_forumhome_randomtopic]">
<tr>
<td class="alt1" align="center"><span class="smallfont">
<fieldset class="fieldset" style="margin:0px 0px 0px 0px">
<div style="padding:0px">
Have you played?<br><br><a href="$vboptions[bburl]/arcade.php?$session[sessionurl]do=play&gameid=$randgame[gameid]"><img src="$vboptions[bburl]/$stylevar[imgdir_arcade]/$randgameimg" border=0></a><br><br>-> <a href="$vboptions[bburl]/arcade.php?$session[sessionurl]do=play&gameid=$randgame[gameid]"><b>$randgame[title]</b></a> <-
</div></td>
</tr>
</tbody>
</table>
<br />
Save the other template just in case you don't like the inner boarders.
