If you want to earn money in games then you should find a game with the passive income, just a little tip for ya
I tried to play a games (forget the name though since its been 2 years) wherein you can earn while playing. But its not worth it since you can only earn few satoshis then there's a minimum amount required for withdrawal which I think hard to reach so I decided to stop.
For me gambling is not a good way to increase your crypto. There are some other ways like trading or investing that is more effective rather than gambling.
