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.
