Is this correct sol?

You need to give some implementation to play in Game class or do virtual void play() = 0; which makes it "pure virtual", otherwise compiler going to complain about that. Also you need to ideally add public: to the derived classes also. Otherwise it looks correct. If you want to make it a bit more advanced, you can dynamically allocate the games in main function and delete them at the end or use std::unique_ptr<Game>

I think if you don't make it public and try to call play on the derived class (which you don't do in your program but may want to do in reality in some cases) then that won't compile. But I may be wrong

Yes, when I create a pointer to derived class and try to access play() its showing declared private. Thankyou sir!!

I usually use struct to denote that it's not an OOP S.O.L.I.D. class but just a bunch of data tied together
