Welcome back! v2.5

Important announcement:

I'm completely reviewing the code, adding important improvements and fixes.

I also tell you that I added the well-known Even Money rule that was not there, it will be a test while I continue testing it when I finish testing it for a few days or maybe a few hours I will do it, turn it all the way up like before.

You will probably find errors more than anything else in calculating the prize or some other extra error, I would appreciate it if you tell me.
