And also, any ideas or strategy/tricks/advices to maximize profits and minimise risks by playing this kind of gamble?
It is nearly impossible to maximize profits and minimize the risk in this kind of lottery gambling by the use of some sort of strategy. I don't think that there is some kind of strategy that will work every time since lottery game is more on luck, winning numbers will always be random and no one knows what will be the winning number.
If luck won't allow you to win there's none that you can do with this type of gambling.
Is more on luck that you'll relied your fate, there's no strategy that will help you to lessesn the chance of losing your money
You'll keep paying in hope that the number that you choose will be hit and give you instant richness, keep dreaming and keep
trying as that's the only thing that will let you to keep playing.
