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.
It also the fastest you'll lose since the house edge tend to make the house win. Actually I don't know why many people are like to play on games that have fast roll, because they seems aren't enjoyed the games and only want to chase the winning.
People should look gambling for fun, because if you're only looking to earn money, you're could become an addict.
