TiTS has a whole casino on Zheng Shi's Recreation deck (the highest point in Zheng Shi) in which you can only play Blackjack with either a robot or Roo.
On the JS version you can only bet 500 credits at the moment but it seems the devs plan to change this to allow bigger bets.
But on the Legacy version you can bet as much as you want (even all your credits which could be in the millions).
Other than that actual gambling they is some bets you can make in the game (like betting money or yourself with Syri in Mhen'ga on who's gonna win a fps game). I don't call this full gambling because you can win 100% of the time if your Aim stat is higher than 20.
They is most likely more 'gambling' like this in TiTs but I don't remember
In CoC2 the only gambling I remember is a group of Minotaurs in the Khor'minos Outskirts. This probably won't scratch your itch since they're gambling small amounts and you don't actually play a game (it's more of chatting with the minotaurs rather than about playing cards)
to clarify with the demon pair, you must beat them five times to unlock their gambling options in the undermountain once they're no longer hostile and it's actually a bet to fuck or get fucked by them.
To be honest, it's possible to make money with online gambling, but it's important to approach it with caution and responsible gaming. Some people have had success with it, while others may not have been as lucky. It's always a good idea to set limits and only wager what you can afford to lose. Oh, and if you're looking for a more immersive experience, you could give this live casino. Just a rec.
Ok I'm 99% sure that this is a bot. But in case someone is considering listening to this robber i have this to say:
Casinos, especially online casinos, are made with the sole purpouse of draining the wallets of suckers that think they can "beat the system". But you can't. These people have been perfecting their method's for hundreds of years and if they ever find a hole in their plan they will repair it. There is a reason card counters gets kicked out from IRL casinos.
Las Vegas wasn't built on winners. It was built on destroyed bank accounts and addiction. Don't gamble.
