Sweden changes it´s laws about gambling. From January 1st 2019, a new law takes place that regulates all gambling in sweden, including online lottery which I use most of the time. Gambling companies are omitted to apply for a gaming license, or else they are breaking the law.

Some of the sites I use right now might be blocked from Sweden to access eventually, some other sites might be granted a licence. Most of them are focused on casino but some might offer lotteries like PB and MM. However I guess ticket prices might be increased. Right now I only pay $3 per line on PB and MM, the lotter takes $6 per line... I´m not sure if they applied for license yet. If they do then thats the place I'm going to buy my tickets from now on.

"The Swedish Gambling Authority will also be able to order internet service providers to set up warning messages for websites offering unlicensed gambling."

Especially frightening paragraph!
