Thomas blinked a bit, that was a bit surprising. He lead her over towards the rotary device saying, "Huh, that's a bit odd. Well, as best I can describe it, most human sports are made as a stand in for battle, with a chance to end up hurt. Gambling is sort of the same, but rather then risk your body, you risk your money. The less money you have, the more you want, since money is used to buy things. Most smart gamblers set a limit that after they lose that much they walk away.
The Roulette wheel had numbers and colors on it. Smiling a bit he said, "Each game is a bit different. Most involve numbers, odds statistics. However, none of that is guaranteed. In places like Vegas it's widely assumed that the house will always win, because they'll comp you rooms and such until you lose."
Thomas asked the woman in the uniform, "What's the maximum?"
The woman smiled and said, "One Thousand a spin sir, would you like to make a bet?"
Thomas nodded and reaching into Raven's bucket put ten one hundred dollar coins on black saying, "In this game, Black or Red is one of the most obvious bets, half the numbers are black, half the numbers are red. The actual numbers pay out more, but if you don't land on what you say you lose. I always like getting a measure of a room by starting out with this."
A few more people bet, as Thomas admitted, "It also matters how much you care about your money. I tend to do a standing bet with myself, I take a few thousand, and if I lose I act like that's the only money I have access too. Means I end up sleeping on park benches for a night or two. It makes it more fun when I win. Money is a standard of living, a safe place to sleep, good food to eat. Most people here have never gone without so they don't mind throwing it away. Money might not buy happyness, but it's alot easier to be happy with a full belly and a safe warm and dry place to sleep. Without getting in the right mind frame, it's hard to enjoy gambling. A poor man might make more on a few hands of cards then he would a week of working a 9 to 5 job. Since money doesn't much matter to you, I'm not sure how much fun it will be."
The last part was whispered in her ear. He knew the Titans had most of their expenses and even a certain amount of discretionary funds paid by Batman. The ball quit spinning and landed on a black six. Some in the crowd cheered, some looked down cast. The woman gave Raven her 10 coins, plus another 10 as Thomas smirked.
