Gameplay is derived from Zuma-type games; the player chooses a key issue (represented iconographically) and then uses a match-and-move gesture to swap their positions. Match three or more and they disappear, the equivalent of volleying successfully in the debate.
The game both acts as a quality piece of interactive media in support of the campaign and a subtle critique of the process itself, since the issues themselves matter less in the campaign than the way they are repositioned.
Debate Night was designed by Gonzalo Frasca, who collaborated on the Dean for Iowa game during the 2004 Democratic primaries.
