I would say that $100 is my minimum amount to budget when visiting a casino. When playing withR$100, the only table game I would be interested in playing is roulette, and only if the bet isR$5 minimum or less. Only getting 10 spins at the table is not my idea of a good time.
Blackjack has the best odds of winning in any game, with a 49% chance of winning. The reason blackjack is so appealing to players is that it is not a game of luck, but rather one based on numbers.
