That's it - my opinion of each site can vary from month to month. I've had a shocking few games on L&L this morning, whereas last week ~Tombstone was throwing out 40x with regularity. It's literally luck of the draw - the games are coming from the same servers with the same RTP. It just feels like this morning that Sky Vegas wanted to pay me more than L&L did. Next week it could be Mecca or Betfair. (But they don't give me cash back, so L&L still have me).
