When playing roulette, the color choice doesn't impact the odds significantly, as both red and black have equal probabilities. However, betting on even numbers provides a slightly better chance of winning.
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.
