Which of the gambling game do you think that is the fastest in bringing profit base on little time duration
if you ask which gambling game is the fastest to make a profit? i will answer, nothing at all. but if you ask how to quickly spend money on gambling, i will answer all gambling will spend your money faster 
because playing gambling for me is risking profits on online or offline gambling sites and we can't beat the bookies. if we win or hit the jackpot, it's just some benefits like bonuses after you spend a lot of your money however, i have a suggestion if just to get a little profit with fast time you can choose below :
- slot
- sports betting
- bookies dice
One of the fastest is with the roll of the dice because it is just took over a second to have an outcome, with the slot games mostly it consist a lot of animations and the roll of the outcome of the spins and regarding with the sports betting sometimes it really takes almost an hour before getting the result it depends what kind of variant you make a bet like game 1 winner, first 10 kills, or score. That's the reason why i guess dice is the fastest but of course to get entertainment most likely i prefer with the sports and e-sports betting at the same time supporting the team I would like to win.
