Been getting quite a bit of this lately at various casinos...
Attachment 2789
On this particular it was at Unibet's live casino.
Of course the link to updated terms is always to the complete terms (changes not marked up) and as I never read the original terms, and don't have a photographic memory even if I had, have no idea what the changes are!
Hope they aren't all slipping in a new clause making payout of winnings optional :)
