I'm not a big fan of slots but dice are also as addictive as the slot machine, they have the same effect on players, all the other luck-based games that excite you will have a lasting effect even hours after you are out of your session, that is why casino operators like their interface attractive and unique from all the other dice games, because gamblers are visually excited at the sight or memory of something that always excites them, I believe it's not only on the slot but all the other luck based game like Dice and especially crash game.
In terms of graphical representation, the dice and crash game is a bit monotonous which is why it gets boring as time passes by. Aside from that it doesn't offer small rewards, it is either you win or lose and that is where slots attract more players. With a variety of graphics, combinations, and possible rewards in every bet, players tend to have more interactive time with slots. If you read the OP you can see the reasons on the quoted content
Every licensed slot machine in a land-based casino or online has a Return to Player (RTP) percentage that players can easily access.
This tells players on average, how much money they can expect to lose from every $100 spent wagering. Despite this figure proving to players that they will lose more than they win on average, people continue playing.
In much the same way that the nicotine rush of a cigarette makes the risks seem worth it, the chances of a big win help gamblers forget that they will on average, lose more than they will win.
every time you push down on the ‘spin’ button on a physical slot machine or an online slot, you are taking control in a way that your brain views as positive. Each time you press the button, the visual whirlwind of colours and shapes in front of your eyes release Dopamine in your brain.
No matter how many times you push the button, the same thing will happen, the reels on the slot will spin. This simple yet effective feedback loop boosts feelings of control amongst players which encourages them to ignore the uncertainty of winning or losing and play on for longer.
Wins on a slot machine game are often followed by the sound of coins dropping from a height, flashing dollar signs on the screen and an array of flashing lights on the slot terminal. This makes a win on a slot a full-body experience that is not only intensely pleasurable and rewarding, but memorable too.
When these wins become etched on your brain, your Dopamine reward system is more likely to be activated whenever you think of slot machines. This helps to keep even the most casual of gamblers interested in slots for a long time, potentially even years after spinning the reels.
These three quoted content makes slots more addicting than any other gambling game. Sure all the gambling games are addictive but research says the number of players playing slots, makes it the most addicting game on the gambling game arsenal.
