Every game is better when you are winning. One thing is assured that you can't beat the house edge, so you are now winning for your good luck only, sooner or later the sakes with red will follow. If only then you can control yourself then you will be the winner whether its a slot or a dice.
But we need to remember that not all games we can win because we need to have luck in gambling games, which is the important thing that we must have. We can be hard to win in the gambling games, and if we force to still playing gambling, I am afraid that the result will not be good for us because we can lose all of the money we have. It will be difficult to beat the house because they will have a way to prevent that, and in the end, the house will take your money without mercy.
That is what he also said in simpler words though, that you might win when you have some luck going for you but once the luck runs out you are going to get busted in no time.
We are basically discussing if dice is a better gamer or are slots better and more popular. If you ask my opinion, slots are much more famous than dice in the non-crypto world because outside the crypto casino I have never seen dice games like this anywhere so since most/all of the gamblers replying here are crypto gamblers they are voting for dice but actually slots are way more popular.
