I've became interested in playing dice games with my BTC but every time I play I lose. Is there something that I'm doing wrong, or dice games are supposed to be like that? (
sorry I'm new to this) Isn't there a guide or tutorial where I could get started playing these games? I don't know how this really works. Any help would be greatly appreciated. Thanks

So far, I like dicecoin.io

No doubts that gambling are the games which are results into the loss and never give definite amount of the profit , here I myself lost much amount of the bitcoin in the gambling ( casino and in also sports Gambling ) .
So here I will suggest you to just control yourself in the gambling and made fun with your bitcoin amount that you have .
In my whole life of the dice gambling I lost About 0.5 BTC , I tried almost every stretagy but lost everything that I deposit because only luck and house edge will work for you and nothing . So my suggestion for you is that control at yourself for the Gambling and use gambling game only for fun only don't be professional gambler .
