Do small bet gamblers have to research about this too?
Could we ask the staff about this "payout scale" or "payout percentage" but will they answer us right?
I don't think gamblers will care too much about it.
Yup, you can always ask the support since the RTP or payout is just based on the house edge but there are games that show the recent RTP in the last 24 hours, week, month, etc.
It doesn't hurt to do some research even if you're a small gambler, it'd be better to play with the best chance of winning since casinos offer so many games with different RTP but at the same time, you'll get used to the percentages as casinos have nearly the same house edge on most of their games which means the average payout is somewhat the same.
