And this game is obviously base on luck, so who knows, maybe in just a few balls, you go and it bounce to the right numbers and that is instant $10,000 for you. So let's see maybe in the next 24 hours we might see someone claiming that biggest hit.
-snip-
It seems that only one person has managed to claim 30% of the total prize pool of $10,000 so far. So there is still $7,000 left to be won. While there's still some time left maybe there are some tips that can be shared? Even if it's based on luck at least tips like determining Risk Level and Rows are close to big wins.

How come he win 30% of the prizepool since the challenge seems to be first come first serve challenge for anyone who hit the 10,000x with the minimum bet $0.5
The one you shared is indeed hitting 10,000x but his bet is $0.3 only which logically should be something not meeting the requirement.
If he won part of the prizepool depending on the bet amount, does it mean that anyone can win a share of the prizepool?
If it is so, so what's the point of having a minimum bet requirement?
From what I sensing that maybe they also have readjusted their terms maybe to attracts more people come gambling and join the challenge.
And of course your are right if there are any adjustment they were meant to also share it across so that their gambler would also be pre-informed that there are some adjustment and or maybe tweet it on twitter for the recent changes could also help to reach more people who where willing to join the casino.
