Yes pumped over £500 playing slots and nothing back, I get up to £20 profit on a high volatile game and it just takes and takes and takes. I play the same slot on Sky Bet and it behaves totally different giving decent wins and it seems fair game. Sky also on request game me details on how much I've put in how much I've lost and what my current rtp is. Asked Betfair for the same and they sent a blank statement saying sorry we couldn't find any history etc... Honestly something is not right with these slots. Even the way they spin is different to sky and Coral etc.. Betfair I put in £500 over a few days lose lose lose. Sky win £100 lose £200 £win 120 lose £200 win £200 etc.. Its a total different game. Scam.
