Blackjack and Memory Game tutorial

Hi, im looking at building a card game similar to UNO.

Now i have looked at these two examples, but as a beginner, the blueprints are still confusing.
Does anyone know of or have a much more in depth tutorial or documentation for these to card demos in order for me to better understand whats doing on behind the scenes?

Thanks

Hi

Have you got a game in mind, there is not exact tutorial for this as far as I can find.

It will change from game to game, depending on what you want.

Hi, thanks for the quick response.

Wanting to do an Uno type game https://play.google.com/store/apps/d...loftUOHM&hl=en.

I have some different rules in mind, but thats what im heading towards.
4 players per game, players get dealt 7 cards to start. Each play consists of placing one card down and drawing another. Cards have different abilities that help win/loose the game.

Thanks
