People who play versions of the game where there is no simple way to tell room coordinates might have an additional challenge here.
Yeah, this aspect is pretty unfair. I imagine some PC players may not even be aware of using coordinates to identify rooms.
I'm really interested in these mysterious prizes (Ripstone don't even mention the EP) but I suppose it wouldn't be very fair for me to participate given I have a beta of the game that facilitates traversing the entire game world in a matter of minutes.
