More and more people become dependant on gambling. What attracts them is hope and even the minimal chance to win big money. Potentially, everyone is a winner, but in reality very few hit huge money. So, there are always those who have lost everything, those who hardly understand that winning is fully up to chance, though there are games with a skill based element to them like poker.
But slot machines and other fully chance-based gambling games present a bigger problem. Thus, slot machines by paying out small winnings to the players keep them at the game and at the same time give hope that the next win will be definitely big. Players should take into consideration that it does not matter how long a player sits at a slot machine. The chance to hit the jackpot every time they spin the wheel is the same.
When gambling, one should also remember hereditary tendencies toward addiction and some psychological factors.
