I have seen quite a number of gamblers who often deposit small amount of money into dice sites, and they could usually spend many hours rolling the dice while waiting for a high multiplier bet to appear, I guess some gamblers does know how to control their total spending on gambling activities and they are just playing the game for their own enjoyment.
Yes, most gamblers will play games for their own pleasure with money that can lose. So it's about wasting money and time depending on how they play, if they play with money that can lose and play when they have free time, then they are only looking for fun that can be gotten from gambling.
