Hi Boney526,
I really don't think that you need to be concerned about any of the eligible tickets being removed from the list. I was concerned about that too, when the drawings first started, but I'm not anymore. It's just my opinion, I wish I could tell you for sure, but I don't see how they could do it and be fair to the players, or to the retailers promoting the drawings. Retailers don't sell tickets at the same pace. I think the first game on the list is Tic-Tac-Toe and that game is still all over the place around here. Even if they do decide to remove some games from the list (which I doubt), I would be very surprised if they did it without first notifying everyone who's registered for the game and giving a window of opportunity to enter the tickets before they remove them from the eligibility list. Just try to get them entered as soon as you can for the next drawing, if you can't get them entered in time for this one, and you should be okay.
Good luck to you!
