There is a bug in the system. For several weeks now there are players (e.g. player, speler) finishing about 100 levels in a few minutes. This is very frustrating.
This happens mostly on Thursday. No reaction from support.
Thanks for reporting this. I will pass this on to the Game Team.
If this happens in your game, please email Player Support from the game's Settings and Help Center so they can take a closer look at the issue in your game.
