I think you have it backwards. If there's no query, there's nothing to put in the partial, but the partial is needed in the case that you DO have a search query. Make a second partial that only has "No search yet" in it. Put that in the else side. In the if side, put this:

render :partial => 'search_results', :locals => @games

Inside your partial, change any instance of @games to games (remove the @).

There's an even easier way to do this, and that's by making a single row of your table as a partial, and saving it with the name _game.html.erb. Then in your index page, add this:

<table>
<%= render @games %>
</table>

If you haven't done so yet, I really recommend a thorough read of the Rails Guide on Views and Rendering. http://guides.rubyonrails.org
