I don't know if player selection is truly random, but it would seem kind of pointless being a new contestant this week when the run is ending when there are people who have been waiting to play since day 1.

Not really, as it’s most likely those contestants will get invited back for the next series.

I don’t think the selection is random, it wouldn’t be a clever idea to leave the casting of a show to chance. The is no logic in the producers doing it that way. The fact the deaf contestant was only there for a few days means they could probably only book the signers for a day or two.
