Isn't it ironic that those games are called physical?
Anyways, see the rules of the jam, of course. Better yet, ask them. But I see your conundrum. What if the jam forgot to explicitly mention what most implicitly expect. That it is computer games. If they made the effort, they will mention something about how linux/mac exclusives are forbidden, since not all judges could run it. But would this constitute a pc exclustivity.
If you need special equipment/software to run the game, it most likely will be disqualified, unless the jam was made for that platform. Like that playdate thingy.
One could argue, that you need no equipment for a physical game that is just an pdf, but one could also argue that this was not programmed for the jam, as it is just a written rule set. I could also submit a storyboard or movie instead of a game to crank this up.
