I have been an early adopter of the Bitcoin lightning network and a strong advocate, I will gladly use the service if it is available in any casinos. The mass adoption of lightning networks will be more effective if there is high demand for platforms such as casinos.

I'm starting to see, and recognize that merely "accepting" deposits through the Lightning Network "because cheap/fast Bitcoin transactions" might not be enough to attract users to actually force them to use it. Altcoins have been doing the job good enough for many users for fast/cheap transactions. But shower thought, what if a casino with absolutley NO KYC as a unique selling proposition, and built directly on top of Lightning like the way DirectBet was built on top of the Bitcoin blockchain?

As an example, a casino like this, but with more games, https://lightning-roulette.com/

By the way, a couple of days ago, the LN network set another record for bitcoins blocked in channels.  I would like LN itself to develop faster, but development is still taking place. 
Definitely, for many people who have bitcoin, it is absolutely superfluous to exchange it for other altcoins.  Extra operations on exchanges and, by the way, paying extra commissions for the exchange.  Most casino players do not need this at all. 
So LN definitely has a huge potential for use in the gambling industry. 
Let's hope that the casinos themselves will be active in implementing LN.

I've seen one site put in Lightning and then after a while remove it anyway despite most people there using BTC to play. Especially the past few years fees have really been cheap enough to send normally, I guess the demand isn't as much as we would have thought.

And yes, maybe I feel more secure paying $1 to ensure I get it there than $0.01 to wonder if I'm doing it right.

It's more complicated than "demand for Lightning isn't high". It's also because, as I said in my post that you quoted, a lack of unique selling proposition for the casino/lack of unique value proposition for the user to use the Lightning Network. It's not only happening in casinos, but also in exchanges as well. As debated, what if a casino, or an exchange was built on top of Lightning and offered NO KYC as a unique selling proposition? I believe it might be something many people in the community would like.

Almost all the casino as well as exchange site take fees base on their own fixed withdrawal fees from where they get commission. If  we use lightning network they will still take the commission though that commission might be lower than the commission which they are receiving right now.

You didn't understand, or didn't get neither the context nor the point. Are you familiar with the TRUE ON-CHAIN casino called DirectBet?


But because as the network became more congested, blocks full, fees high, it became impractical to use DirectBet. BUT, what if a casino like DirectBet was built on top of the Lightning Network? I believe it might also attract, and give users an incentive to use Lightning.

That casino is in DEMO mode and I think it's very good, I'm really not much of a Roulette player, but they have a good concept, besides the fact that the game is fast, and it has a particularity that I don't know if it's currently lost, when I was a few years ago in a traditional physical casino, the roulette had the cer(0) and the double zero(00) in this one has only one zero(0), for me that way it has more chances of winning more when they have so many options, and particularly if it is that fast and each deposit through LN one can play like this, at least I would be hooked to play slots, because with little you can enjoy a lot, and this in some sites is limited to a certain amount, but as it is in LN it would be a low minimum amount to attract both big and small players.

The only reason to use lighting network is to make quick transactions.  Because Bitcoin's block takes a long time to be confirmed.  Which is often the cause of annoyance among gamblers. I use the lighting network for deposits and withdrawals.  Because it charges less gas fees.  And completes transactions quickly.
