I made a Blackjack card game with Unity between Friday and Saturday and I pushed it to my github. After a lot of refactoring, the entire source code is available here. If you wish to copy the link, it’s here: https://github.com/joaokucera/unity-blackjack.
There is also a webgl demo here.
There is no license, no condition, download and use it as you wish. I hope this helps you to study #unity3d and if this help you then give me a github’s star.
