I've found that even though you've been on the app for a long while and spend alot of money on coins, packages ect.. the system tends to not give as much back in winnings as I'd like to see especially if I'm spending money on it for a bit of fun. It's more so taking then giving back, would like to see higher chances of winnings in games if we're committed VIP members who purchase constantly while on the app, it would definitely make it a better experience.
