Well, it says expiry price > enty price + 2... Your entry price was 5 and expiry price was 7... because it says greater then instead of greater equal you lose. Is this so complicated?
I like this game.. Sometime they have problems with the payout but they always payed after telling them about the problem.
Of course you can not always win.. this is gambling.. If you hunt for the big win it is very likely that you first lose big ;-)
