5 home games are on BTN Plus. You have to pay for that. I think you can get just the Minnesota games for about 10 dollars a month. You can cancel at any time.
I've done that for a couple of years. Quality of reception is ok but the announcers are students and pretty bad.
3 games are on the BTN network. I think you can get them free with the BTN2Go app.
2 games are on ESPN 3, 1 game on ESPN 2.
