The lot I had this Wednesday go up to 4430 but I've yet to do those I'm a bit behind this time. Been playing other games. Well done to you. I'd love to know how many are at this level. I'm on 4412 at the moment.
I completed it the first time back in December and then I was getting new levels every time I got a buddy challenge which I would complete. Now I guess I will only get 30 levels a week to complete. I am glad I finished it but sad because I want more levels lol
