I left some comments to see if I was understanding it correctly, it is not necessarily wrong.

body: I wasn't able to solve a problem that occurs when a game finishes and the amount of coins needs to change but for some reason it stays on 1000 every time idk why. I will review it in the followings days, and also solving the SonarCloud's problems, but if anyone wants to see the code if he/she finds a easy solution for this feel free to do it. And if someone solves the issue, can be only the funcionality and then the tedicious changes of coverage and more, can be done by me, no problem.
