Not sure exactly what you're talking about, but yes, all entries in the competitions are done completely from scratch. You're allowed to use *very* basic code like window creation but everything from there needs to be hand-made, no pre-made game engines or anything like that.
Also, all art, music, and the like must be created on-spot during the competition, nothing from the internet.
