Well, I haven't broken the law it seems.
Their chat has been busy because of Grand National issues it seems.
Chat transcript below, that clears some of the issues of this thread up -
Chantelle : Hello welcome to Betfair you are chatting with Chantelle. How can I help?
Me: Hi, I signed up to the casino yesterday, and have played with a bonus, there is a condition attached where slot play is restricted to 2 hours on a specific slot. I need to know whether I have exceeded this yet on the Gladiator (non jackpot) slot
Chantelle: Sure, let me check that for you, one moment please
Chantelle: As per terms and conditions, you can play up to 2 hours per session
Chantelle: Seeing as you stopped playing at 19:56, the next time you launch this game you will start a new session, meaning that you have another 2 hours and you must not exceed 500 spins
Me: Ok, thank you - have I been within the 500 spins for all my sessions since signing up on that slot ?
Chantelle: Yes, the first session you played had 479 spin and the second session had 109 spin
Me: Wow, that was lucky - so you can confirm that currently I haven't broken the t's and c's, and that each new session allows for a fresh set of 500 spins, and/or 2 hour limit on one specific slot?
Chantelle: Yes, I can confirm that you have not broken the terms and conditions as you have not exceeded the 2 hour limit in a session and you have also not exceeded the 500 spins allowed per session
Me: Many thanks. Finally, a case scenario - if I play for example - 499 spins then log out and back in again within a minute or so, does the new login to carry on playing the same slot mean a new session, so theoretically, you can carry on playing pretty much straight away ?
Chantelle: In this case, if you had to play up to 499 spins, we would recommend that you log out and wait a minimum of 30minutes before logging back on and continue playing
Me: Brill, that clears things up. Does casino live support have any direct link, or do I always have to go through sports live support and then get passed here (which takes a lot of time)
Chantelle: I apologise for any inconvenience. Due to the Grand National races we have been extremely busy this evening
Me: Of course, thanks for your help Chantelle.
