My Keno sessions always looks like that, usually its like 40-60% rtp, on a good day its 60-80%. Stake originals for sure is turned off this year (especially last 3 months and this "christmas special" month).
Nah seed,nonce,luck and other bullcrap don't exist here. With Originals its just simple = it eats your balance for months and then throws back "lucky" big win.
From saturday weekly boost i got 500x within 10 spins on keno. Mines are good too because chances are better for hitting like 2500x than hiting 500x on keno.
