A/N: On one of the tumblrs I run, Twinings and I offered ourselves up for one full week of filling fic prompts for our readers, varying in length from a hundred to a thousand-plus words. The project has been dubbed the Free For All Fic For All—or FFAFFA for short. This is one of those stories—and this is the boilerplate author's note you'll see on all of 'em.

Prompt: Riddler, Puzzler, Showdown.

"Oh, really?" Puzzler leaned forward, never taking his eyes from the Riddler's. "Well, then, why don't you do it already, if you're so clever?"

Clack, clack, clack, clack, clack, clack.

"All six of your remaining men in just one move," the Riddler said smugly. "Tell me, is there a checkmate equivalent in Chinese Checkers?"
