You may be interested in reading Wittgenstein on trying to define what a "game" is. In short he found that there are no conditions necessary or sufficient to make something a game. Nevertheless, games exist.

It’s amazing how much Wittgenstein anticipated. You can see here how his philosophy anticipated meaning as being fundamentally a probabilistic superposition of the relationships between words, with no fixed form, predicting today’s model architectures:

> for instance the kinds of number form a family in the same way. Why do we call something a "number"? Well, perhaps because it has a direct relationship with several things that have hitherto been called number; and this can be said to give it an indirect relationship to other things we call the same name. And we extend our concept of number as in spinning a thread we twist fibre on fibre. And the strength of the thread does not reside in the fact that some one fibre runs through its whole length, but in the overlapping of many fibres.
