Maybe more tickets would be a winning chance too,
I also will never leave funds in my account for a long time, I better play it or make a withdrawal, if I want to play again then I deposit it again.
But @Chato1977 has been saving funds for a long time.
It is not that big, I can even say it is cheap than most other similar lotteries in other casinos.
What you need to remember, you get a ticket by wagering not by buying it so you are not losing $10 for every ticket.
You can do small bet and do thousands bet on dice game with low payout or with any strategies you wish.
Other important thing to remember, 1 ticket has the chance to win $5,000 although the chance is so low.
There are players in roobet that can bet 20,000usd in single roll while some put only Penny just to try their luck.
It doesnt matter if 10$ is big or small but the capacity to play and partake is what Roobet needs here.
I have to make approx 100 bets to win 20/30 bets; So if you can't effort $10, how will you be an active gambler & how will you be able to acquire your ROI by wagering!
Yes, gambling is entertainment but if there is no winning/profit then there is no entertainment by losing money. as much as you can effort as much as you will get chance of winning.
So, for getting $5000 lucky winning chance, $10 is not a big deal at all.
