I’ve had around 20-25 but I grind it a lot. I’d say 3/4 have been 0 bonuses, 10/15 have been around 50x and the rest have been 75x -150x plus.
Seems to bonus easier on lower stakes compared to stakes around £1 in my circumstances.
Basegame seems to pay more than the bonus most days.
Also seems to come in more if I spam click rather than autoplay.
