Hello I have been playing for many years. I'm going to level 4963 And I have never, never paid a penny. You can pass all levels without having to buy or pay something.
If you've already seen the vids for the level (like this) & you're trying to beat it with NBU (like that player), perhaps you'll get a lucky board soon.
Level 13294 is too difficult for me am beating in 22 moves and the moves can't beat me to win the level am so bored about this level it is now for weeks am trying it and no success
