Different loop based on category name

I need to show a differnt custom loop depending on what category the current page is filed under.

There are about 7 or 8 categories, each needing their own little loop.

Here is my current loop code

<div class="offer rounded shadow">
	<?php query_posts( 'post_type=offers&category_name=home-page&posts_per_page=1&orderby=rand'); ?>

	<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
		<span><a href="<?php the_permalink('');?>"><?php the_title('');?></a></span><?php the_content('');?>
	<?php endwhile; ?>
	<?php else : ?>
	<?php endif; ?>
	<?php wp_reset_query('');?>
</div><!--/.offer-->

I need to be able to show a variation of this loop for each of the 7 or 8 categories.

Any help would be great.

Thanks in advance
