I think it depends on what system are you using to play the game, but I’m at the top of the world leaderboard, and it’s apparently way too easy to fake. I’ve been at the top for quite some time now. I’ve been the first to beat the game time and time again. I’ve never spent a dime on this, I don’t do any candy club or whatever that garbage is, I beat every state on my own merit.
I play on my iPhone. I’m on level 4681. As of today, the highest level possible is 4745, so I’m 65 away from the top. Tomorrow (like all Wednesday’s), King will add either one or two more episodes of 15 levels each, so to get to the end, the highest level will be either 4760 or 4775.
There are definitely people ahead of me since we now have 5 person intra-episode races to complete each level.
