I’m learning Elixir by myself for fun now. I have basic Python knowledge before. I think the best way to learn a new programming language is to do some real projects. I’m try to create a web based poker game. The basic unit of the game is the table. Different tables have different game rules. e.g. Texas Hold’em table, Omaha table. etc. But as a functional programming language, Elixir has no class no object no inheritance. My question is how to implement a structure that can associate with different game rules?

Just use different modules for different games. Maybe also create a basic module with
@callbacks and use it as a@behaviouron the implementation modules, to define a common interface for them, and ensure they have the functions the base game module calls.kokolegorille
If You like Poker with Elixir, there is an old post about it here https://tokafish.com/playing-poker-with-elixir-part-1/ You might need to adapt for newer version, but the post is nice.
Other games I often saw, Tic Tac Toe, Tetris…
I wrote a little game engine for go here elixir_go | Hex

I would take care not to link the game implementation (e.g.
:card_played) to a GenServer. You can implement all of the logic with pure modules and functions.To Spawn, or not to Spawn? by Saša Jurić gives a good overview about when and how to reach for processes and even talks about an implementation of a card game to boot (Blackjack).

I believe that this is easiest example for board games (as far as I remember table in each game have only one event like card played) at same time + time for players in their rounds to think about next move.
