I didn't like the article because It use as example the low risk plinko while most users like to play with the high risk versión, so, It would be nice if you add the technical data of the hard version.
From what I understand the odds of getting the x999 is like 0.0034%, but im not sure, I make the math some years ago and now I don't remeber the exact number.
I don't know the exact % as it has been years since we worked for luckyb.it, but we do know that the odds of hitting the x999/1000 are 1 in 32000 bets. It's a little higher but basically 1 in 32000 bets will hit the edge.
