This is not looking good. Firstly, they are NOT informing ANYONE about this, yet they are using a lack of telepathy as an excuse to void winnings for players who presumed the casino would remain open, and that they could finish their WR within the normal rules of the promotion.
A REPUTABLE casino would notify all players concerned that they were not going to be able to play beyond a given date, and to finish any remaining WR and withdraw any available balances before this time.
SEGA have closed on the quiet, leaving players to find out TOO LATE to do anything about finishing WR, and making an orderly exit from their accounts.
SEGA have lost the plot, they have ensured that they will go down in history as not merely incompetent, but ROGUE, because in some cases, they have tried to "do a runner with players' money". Even if such cases get sorted out, the damage has been done, and the SEGA brand image has been tarnished for some time to come.
It looks more and more like EVERY country on the PLANET is now an "excluded jurisdiction", yet SEGA casino are STILL trying to make out that they have NOT closed, but have merely widened their exclusions.
It would not make sense for such a wide exclusion list to be PERMANENT unless they WERE closing for good. If they were merely going through a bad patch, they would intend to reopen to many of these excluded countries in the future, and would NOT want to damage this by making it look like a PERMANENT decision.
