Some people enjoy online gambling; others have to gamble. What makes some people risk everything on a game of chance?
People gamble to win money. That’s the reason millions of people consistently purchase lottery tickets. The odds against a large pay-off are astronomical, but people continue buying tickets. Occasionally, they’ll win a few dollars. That’s precisely the reason people keep coming back. Winning even a tiny amount positively reinforces the idea that winning is possible. People who spend $50.00 on tickets and win $10.00 don’t consider that they’ve lost $40.00. Instead, in their minds, if they can win $10.00, then a $100 win is just around the corner.
