As to how i understand this, the games with the biggest win has the biggest risk that follows as well, taking the risk is what makes it worth a deserving winning as all hope could have been dash way in playing games with high risk, that's why when you place a bet you discover the higher the numbers of games selected the more the risk and the total winnings, while the more you increases your stake as well the more you're vulnerable to loosing the entire stake for naught and the more are your winning amounts increasing, but for having the biggest win with the Lowest risk only take a luck and this comes once in a blue moon.
Just case to case as per luck happens to you, a big win like lottery jackpot for example which you can buy one ticket that only cost you less than a dollar can be converted to a million if you manage to take all the winning numbers, that kind of luck will change up the entire lifestyle of a person. Not usual, and only a few people can be that kind of winner.
More or less, the person who takes the gamble understands the risk and just hoping that luck may back him up and give him the jackpot.
We don't know when and how, but if lucks permits, then it will happen to you.
