So far, I only play blackjack and poker if I am in an online casino, because I think that this type of gambling is quite easy for me to earn profit compared to roulette and slots. Blackjack and poker are very popular in casino gambling I think, and I only occasionally play on roulette if I feel that I have no luck in blackjack and poker. I've even borrowed money just to play poker and I can repay the loan less than 12 hours.
