other jams have same rule, e.g. Godot Wild Jam.
I havent seen other jams doing this so far.
Many jams have this rule below. I just saw it in their code of conduct:
but it didnt say we couldnt join other jams which is what I was asking before.
You're free to join other jams, we only are concerned that you're submitting original work to this jam, as in a game you created specifically for this game jam.
Thanks for confirming!.
