A Closer Look At These Sweeps Casinos
TheBoss.Casino already had a long excluded territories, and California only adds to it. 
Now, there are 22 excluded states, including Arkansas, California, Connecticut, Georgia, Hawaii, Idaho, Iowa, Kentucky, Louisiana, Maryland, Michigan, Mississippi, Montana, Nebraska, Nevada, New York, New Jersey, North Dakota, Ohio, Tennessee, Vermont, and Washington. 
As for Grand Vault, their list is much shorter, including California, Connecticut, Delaware, Hawaii, Idaho, Louisiana, Michigan, Montana, New York, New Jersey, Nevada, and Washington.
While LuckySlots doesn't list California yet, Sweepsy confirmed that it tried to play with an IP address based in Los Angeles, and they received the message “Your access has been restricted based on your IP location.”
We also tried this and can confirm the same message. 
These Moves Make Sense
Of course, with AB 831 being signed into law and going into effect Jan. 1, 2026, it's only a matter of time before every operator leaves. 
Some are deciding to get out sooner than others for various reasons, including not potentially facing issues should anything unexpected slip through the cracks. 
Conversely, there's a platform, WOW Vegas, which plans to stay open right until just before the clock strikes midnight on Jan. 1, 2026. 
So, these moves make sense now to mitigate any further issues potentially. 
That said, we'll continue to monitor which sweepstakes casinos leave and when, leading up to Jan. 1, 2026.
