This game design challenge, hosted in 2009, took place in two phases. In the first phase, a game name was randomized (for example, "Goblin Lovers"), two game constraints were selected (for example, "uses physical motion as a key component to resolution vs. uses images as key component to resolution"), and two designers were paired together. These three elements were then matched up. In the second phase, the games were designed, submitted, and judged. Thus, two designers would generate eponymous games differentiated by, at least, the constraint mechanic. Note that in several games, one of the assigned designers did not participate in the challenge beyond the initial setup.
Twenty-two games entered the at Phase One, at least twelve entered Phase Two, and six were selected as winning entries.
The results were:
Two games in the competition have very similar names: Hell 4 Leather and Hell for Leather. Both of these games were subsequently revised and commercially published.
