Exactly how much money does this horrible company need to make before it will just release a game that remains fun and doesn't eventually devolve into a naked money grab by frustrating users into spending money? Level 581, level 601, level 607, etc. are all complete garbage and it only gets worse with each new array of levels. You just have to play them over and over and over and hope the game board falls just perfectly to allow you to pass. There is no strategy, nothing learned from attempt to attempt that is useful the next time, no knowledge acquired that is useful to the next try. It's just a waiting game with each failed attempt trying to tease you into paying for extra moves or that key booster that would allow you to pass but, oops, you don't have.
It's not fun; it's insulting.
You're just a bunch of [**Removed by CM - rude content**] for your most experienced users and that becomes obvious to anyone who plays your games long enough.
I only play out of spite; I've passed 99 percent of these levels with 3 stars, haven't spent a dime, and will never do so. I bet most people who played as long as I have are the exact same way. [**Removed by CM - insulting content**]
