Dice would be the fastest one to make some bucks. You win or lose. This will be done in a few seconds compared with slots that it takes a very long time waiting for the multiplier to come. Actually this is depend on our luck. If people are suffering the lose and just take them were not lucky enough in gambling. If you are lucky enough and you can get profit from doing various game. your luck is the main concern.
Why Dice is fastest? You can go all-in in ANY game, like roulette, poker and so on (I've said it before here). So I would sum, that ANY gambling game CAN be fast profitable (the same as fast lose). This depends not from a game you choose, rather from your gambling style
i can agree with you here, any gambling game can be of profitable if you got lucky, but of course, if you're not, definitely, the fastest to lose money. don't know why people are asking this kind of question in the first place? are they hoping that someone will confirm that a certain game will give them the fastest profits? i don't think someone can guarantee such gains.
Their is no game that is so fast and easy to win, all games are risky and if you are luck you will win fast that you will be so surprised and be happy, there are games too that are also easy to lose so fast. Playing gambling is by lucky, experience can also increase the chance of one winning a game.
