So the .0001 jackpot got pretty high the last couple of days. It was around 4BTC. Is that why it doesn't show on the Big win list? Because it is so small compared to the higher bet jackpots?
That's correct. The jackpots that are shown in the list are based on the absolute size of the prize paid out. This unfortunately means that the big wins list now mostly just shows the huge 0.2 BTC Slots jackpots... :/
