Of course it's impossible to hit that number in "every spin" because freebitco will get bankrupt easily as everybody will play on hi lo with the jackpot on, however it is possible to hit that number sometimes.
I was actively playing hi lo game on freebitco before and I can get that number but the only problem is that I just play normally without activating the jackpots because I know that it will only drain my money fast and as usual there is that regret feeling because I can sometimes hit that number within a few rolls only on some of my sessions. My only hope for now is to win some decent prize in the hourly free roll as there's no risk on this one.
I never pay attention to whether I have ever got the jackpot numbers or not, because I used to play auto bet during promotions and leave it to do another activity, I think the jackpot is only played by big players or those who are indeed trying their luck only.
Gambling is a game for people who have a lot of money to get entertained because of course if you are just having a limited amount to play there's a chance that you didn't get hit that wins because you are lack of funds but if you have a lot of money to play there's a possibility that you might hit the jackpot upon continuously playing sometimes we didn't get hype in wins because we use the auto spins for the fast games, and our main goal is to hit the jackpot.
