so it is difficult for them to enjoy the gambling games.
To be honest, I don't see how you can enjoy the gambling games. Casino games are very primitive, they are conveyor and standard, they have the same principles and just slightly different design. These are not professional video games, like from Sony studio, for example, this is not an artistic product, with a plot, history, game mechanics, where you can really enjoy. Therefore, I would not complicate things where there is nothing to complicate. You can only enjoy casino games if you win. This is their only task and people play them only to win, and not because they get colossal pleasure from the process of the game, which is constantly repeated and has no variations.
It's enjoyable if you are winning but it becomes stressful when you are losing that you can get frustrated, regrettable, and just sad that you made a wrong decision to gamble.
The UI of the games now is truly colorful but you are right, it's not like the RPG games or adventure games of the consoles like Playstation and not even close to Gameboy's advanced games with a story, twist, and grinding methods.
Slots are repeatable games which means what you get now could also come out later and they will just recycle those depending on the algorithm that you will get. It's only enjoyable when we are getting the upper hand and our money is doubling or maybe more.
