Slots are easier to make gamblers addicted, because the games in slots are varied, with an interactive game model that makes players unaware that the icons are for betting. The absence of waiting time for results makes gamblers quicker in taking action. Unlike sports, we have to wait for the results of the match first before we know whether we lose or profit. Don't forget too, there is also emotion control in slots, for example, the more often you see the scatter symbol, you will start to think that you are close to free spins. this triggers you to continue spinning.
