I mostly played on Duelbits and Roobet. Honestly, right now, I can't think of which one of the sites that I am playing is my favorite.
For the wagered amount, I am a low roller, but I gamble a lot almost a year ago that's why I have good amount of wager even though I mostly bet the lowest possible stake ($0.2).
My biggest win was on Sweet Bonanza Xmas, it was around $1.3k.
