“Nightclub Promoters”
Casinos, particularly in tourist centers have watered down odds on games to the point we would consider them to be a scam. If playing roulette, find a double zero wheel, or better yet seek out a single zero variant (which can be found at Plaza).
Similarly, with blackjack find a table that pays a traditional 3:2. That could require playing higher stakes on the Strip or heading off the beaten path to find a game. If you are staying on the Strip, walk a few blocks behind Bally’s to Ellis Island where affordable 3:2 blackjack can be found.
