Again I present another example:

If I deposited 4mbtc and accepting the freespins bonus.  Spin through the spins and win the maximum amount allowable by the bonus and then clear the 40x playthrough, despite this incredible achievement I would actually have less money than I deposited. I would have only 3.3 MBTC but I deposited 4 MBTC.

This shifts the favor in advantage of the house by such a high amount that the game is nearly impossible and should not be described as gambling st all.  It's either purely for entertainment and not really gambling or its a scam that used magic tricks to calculate their players balances. 

Again.  No other casino operates under these corrupted rules and calculations.  It's asinine.
