Could anyone help me with the options that is available for a Swede?
Only Viasat?
No guarantees, but if it's the same as last year, there won't be any blackouts in Scandinavia, meaning if you're able to sign up, you'll have access to all the games.
To be able to sign up you need a vpn, proxy or dns service. You can try hotspot shield or a similar service, there are plenty of them.
If games are blacked out, you will need a high speed vpn account (will usually cost $5-10). Note that this is a breach of the terms of use, and that nhl.com threaten to charge you $100 and consider taking legal actions if you try to circumvent blackouts.
Then there's always free streams with streamo (streamo dot atspace dot com) being one of the better.
You can pm me if you need help getting this stuff working.
