A series of compilations, the first two collecting games made over a separate weekend-long event at Glorious Trainwrecks, the third a last-minute IGF entry with some old games, some new. Like their 'Klik of the Month' events, each game is made within a two-hour time limit; though cheating is encouraged! Because of this, the games are often based round simple things: a joke, an odd mechanic, a bad MIDI version of an 80s pop song, et cetera. As the name suggests, most of the games are made with Klik & Play, though there are no rules restricting how the games are to be made.
The compilations are huge—the first containing 103 games, the second 529—and you're not likely to play through them all. The compilations' pages will have more information regarding their contents.
