TY... Will be taking a look at correcting this shortly!
They've had this "error" for as long as they've been in business.
Notice the quotations around "error."

This will not be corrected shortly.
In fact, I'm guessing that this issue will take weeks to fix, all the while pocketing your extra money.
I don't recall ever seeing any other casino use these shady tactics to skim money from their players.
This is a nice little strategy Bitcoinrush has going and it's about time someone called them out.
Let's see how "shortly" this gets fixed.
In the meantime, I'd avoid this shady operation like the plague it is.
