Lottery betting has various ways that gamblers can do to get good numbers or numbers that can increase gamblers confidence when buying them that the numbers are really correct and worth betting on.
But basically the lottery is bet with an RNG algorithm or has random numbers in its performance, of course luck will be very influential in this bet and this is bet with very pure percentage of luck.
There are some people who believe that buying more tickets will increase their chances of winning but to me that is an absurd idea.
There are lots of random numbers and of course, from series of numbers, you can never guarantee that one of them will come out if all of them are used to buy lottery ticket.
It is better to bet smartly and as much as possible avoid careless or unreasonable methods to avoid significant losses.
