I think I have finally finished the game. My smallest tile is a 4 and the largest is 131072. Almost impossible to finish the game without the UNDO. The only reason I question if I finished is, when I got the 131072 tile, the game said "Congratulations!, You win 131072!, Your next goal is 262144, OK". Why would it say that if it was not possible?
