Hey guys, I have been using this faucet for a month, but have been only getting rolls of 0 - 9885 of 0.00000021 BTC. Anyone rolled above that? Or they've tweaked something? 
i have experience hit the number more than those amount of rolls but it was happened only several times and i think the percentages to get rolls more than 9885 is less than 10% and that's why only several people had experience hitting those number Nothing has been tweaked and you can work out the probability of hitting each prize level from the numbers displayed. So level 2 is 9886 - 9985 giving 99 chances in 10,000 possible results. It's all provably fair and just pure luck if it comes in. The top prize of $200 is a little harder to get as numbers are rounded you need to roll above 9999.5 to win so it's a 20,000:1 chance.
I have been playing a long time and had many rolls in the 1st 3 levels but none higher, that is statistically quite normal.
I dont see your point. There are 10001 possible outcomes and the highest one is just one of them so, in my view, chances are 10,001:1. I dont understand what you say about rounding numbers, they are integer, whole numbers, not fractions.
Ive played over 2600 free rolls and I won one third price once (9994 9997), some fourths (9986 9993) and quite a few fifths (9886 9985), one of them today.
I play this faucet and brother site freedoge.co.in and, on average, every week I get a price (number above 9886).
