When I was younger I used to play online poker, mostly on the phone, I think the app was called zynga poker??
Is there a trustworthy website, maybe open-source or run by good people that has a decent user base?
Edit: I don't want to gamble for money, just for free and virtual chips.
There are devices that measure radioactive decay for operations where truly random numbers are very important. Or something like that, I am not an expert, sorry.
For fun?
