No way to do an easy money in gambling. And the usual way is betting or rolling on the dice and wait for your fortune and shows up "win" that's the easiest way.
Gambling relies too heavily on luck and there is definitely no easy way in gambling because luck comes and goes to us as they please. Luck can not be predicted when it will come to us, luck can come anytime. Sometimes luck does not come when we really need them.
It's like you can win an easy win once in a blue moon. But there are times that gamblers will win an instant easy win but it will be recovered again when they gamble and will be losing from their bets. This is the life in gambling, the path is really unreliable and no one can tell you a definite way of winning with an easy way.
