Idle games
Do you play any Idle games? And if you have played many, which is your favourite?
I have played a few, most I don't remember their names, Cookie Clicker is the only one I remember.
But I can only do a day or 2 at most then I never come back.

the one with the egg on the phone which you click infinitely

Try out Forager. It's a game that allows you to grind to the point where you become OP. It's on many platforms, including PC and mobile, and is super user-friendly
