The snake addAll method currently has the same restrictions as the offer method when it comes to the tiles it allows. The plan is to allow the addAll method to allow tiles with two (maybe more) directions set, so as to make it easier to be used to populate a snake with a collection of tiles, possibly even with another snake. This would allow for greater flexibility and could be used for different game modes.
