Better late than never, the NWHL announced today that all games this season will be live streamed for free on YouTube, which they're calling The Cross-Ice Pass (although the YouTube channel itself is not linked on this page).
The Cross-Ice Pass was first mentioned with the release of season ticket package information, the summary stating that season ticket holders would receive 10% off the price of live streaming. At that time, it seemed like the service would be a paid platform similar to NHL GameCenter, so the news that it will be free for everyone is somewhat surprising.
