All you have to do is google free streaming of tv stations and then go through every google results till you find one that works and has your games on it.

The problem is that the free ones are only free long enough to reel you into paying for them once they start buffering all of the time or the sound goes weird after an hour or less of viewing, in other words nothing is free forever so just plan on googling for new free tv services everytime the one you're watching goes flakey.

Roku has some free content, including some games but I have no idea which games as long as I'm not into sports.
