Free players beware. I played from Kong until 18th level and then suddenly got a Flash player notification. Updated Flash an everything else without success. I requested support from Kong AND bigpoint and got no reply. After that, I went directly to bigpoint.com and started a new account, where I played until 18th level and got the Flash player notification again. I'm afraid this is not a bug but an intentional deception of people who are not willing to pay for the game. I shamelessly admit that I am one. If you have played for free beyond 18th level, please forgive the assumption.
