I play dice every week ends, i think it's about 1-2hrs playing. Still it depends on how much money you willing to loose. If you put big amount and bet small it will last long.
Only play dice , and so I will only spend at most 1 - 2 hours on it each time. When I am free, I could be playing dice a few times a day.
I am not playing everyday Dice because than it will cost a lot of money for me, I play maybe 3 days in a week for some 2 hours and that is good enough I think.
If you are playing a long time and that much than the chance will also be high that you can lose a lot of money.
