I personally don't trust these internet casinos, unless it's video blackjack but I still have my doubts about it. Digital gamble games are programmed to generate a fixed amount of profit, random values generated by computers are never truly random, they're based on algorithms. However it's possible that you win by 'throwing the dice', they don't always win otherwise nobody would play it. But it needs an investment and chances are bigger that you lose than win, otherwise a casino would make loss.
