The guy likes to play arcade to pass time in free mode, he likes playing at Betfair. He has quite a bit of cash in Betfair, and he starts playing for real money at Betfair without realising it because he has that nice amount in Betfair.
He created his own luck by being in that position, chances are if he was at any other casino he would not have been able to do real-mode at £180 a spin as he wouldn't have the balance (unless I'm wrong and he keeps large balances in many casinos) therefore he created his own luck.
Or does that sound like twaddle?
If it is I'll get mi coat.
