It is very high-betting return.
I have a feeling that only winners shown proofs of their wins, losers don't want to show proofs of their losses.
It makes sense.
Just wondering how many rolls he did before he got that 16x.
No matter how many rolls that he might do because on dice game is just matter of luck whether you are going to hit and even you can do it in the first bet, soa as I can say this is nothing more about luck that play a role. And btw 16x is not really a big deal, so might hit it under 1000 rolls or 100 rolls but if you comparing it to 990x or 9900x then this must be really hard to hit
when luck will showed up as long as the player/gambler is aiming to hit that target, their determinations will give them a chance to taste
the sweet success.
Also, not to forget how deep the bankroll and how well they manage to extend their stay waiting for the big one.
