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.
For example, Blazing 777 from Bally's offers you more winning combinations based on how much you wager. Another game that offers players better prizes depending on how much they wager is Mega Moolah, which enters you into mini, minor, major, or mega progressive jackpots based on how much you wager.
