No extra in app buying?

Actually?The final time l play this recreation was virtually eight years in the past. I left the sport due to uncountless grinding of unlocking new sharks.Nevertheless l discovered it on my recreation cross listing right this moment,and it stated that there's no adverts or buying now. So what’s going to or not it’s?Is it not grinding anymore? In that case ,I’m will to get pleasure from it once more.BTW, I'm an English newbie. So forgive my awkward phrasing.
