I recently heard of an old Saw flash game/ARG on the official website from the 2000s, that led to a teaser for the next movie (I think). I haven't been able to find it anywhere online and it's probably lost media, and I get that Saw is already an overly convoluted franchise, but if someone were to find it, could it be added to this/the Saw timeline (if someone's made an isolated one)?
From what I've read you would play through a Saw game, so unless it obviously can't be canon I would assume that it is.
