I used to play dice because i thought i could make profit, stable profit from it, obviously i was wrong, you can't win in the long term, that was my only purpose of playing dice, other than that i do not find it fun or entertaining unless im winning money, i would not play dice if money was not involved, so my question is, why people still play? Im sure 90% of people know what your odds are and that strategies don't work, what is their purpose? Do you guys really have fun playing dice? Watching a number appear on the screen?
Well watching a number appear on the screen is pretty much any online gambling and in fact a lot of offline gambling as well. Sure, they take different forms, but in the end its the same result. Even with lotteries, numbers get drawn, sure maybe a fancy ping-pong ball machine for some entertainment is involved, but in the end they display the numbers on a screen and that's that, win or lose. Same with most slot machines and electronic devices, the random numbers behind the scenes may display as cards or cherry's or take some other form, but most of the time it boils down to some random number being drawn.
As far as your argument that you can't win in the long term that is true for just about all gambling as well. All casinos have the house edge, or they would not stay in business. State lottery's have a huge edge in that they only pay out 50-60% of what they take in to begin with. So unless you are that lucky guy who just bought one lottery ticket in his life and won the grand prize, you will come out losing in the long term. I know people who have won lesser amounts ($50,000-$250,000) and over the long term they have probably gambled all their winnings back.
In the end most people play for the entertain value and "rush" that gambling can bring. If done in moderation I liken it to being no different than spending my entertainment dollars elsewhere. A dinner and a movie, a round of golf, a day at the amusement park, many of these activities will set you back over $100. If you spend $100 a week or so gambling, really no harm done, and even if you lose over time it is still fun in the moment when you do win.
Basically it sounds like you need to find a different game than dice. However, I think most any gambling games are really not that fun unless you are winning money.
