Seldom go to casinos, only times I have is when a group of friends wanted to go. In casinos, max win and max loss has been somewhere around $100.
When I was 18 to 26 or so, played a lot of bourre' in the golden triangle area and Louisiana. Biggest night was just over $2,000 (as I recall, but has been long ago) in winnings and half that in biggest loss. Once Texas Holdem became popular, played in cash games and biggest win and biggest loss was in he $500 to $1,000 range. But those are the best and worst, the outliers, Generally, the numbers were closer to $100 or $200.
Also when I was in the 18 to 21 or 22 time frame, we had local games on Friday or Saturday night like every other week. We single guys would gather up after our dates and join our married friends around midnight. These were low stakes games, maybe we each brought $25 to $50. It was a party night for most of the guys, a night out, so lots of beer. I would drink little or nothing but was happy when they had too much and didn't think clearly. I would win $75 to maybe $110 most every time, which was good money when making $2.41 and hour, lol
