The national collegiate women's ice hockey championship is a big game where the best women's ice hockey teams from colleges all over the United States compete against each other. It's like a big race where the teams try to score the most points by shooting a puck into the other team's goal.
Before the championship, all the teams play a lot of games called "regular season" games where they try to win as many as possible. The teams that do well in the regular season get chosen to compete in the championship.
When the championship starts, there are different rounds where the teams play against each other to see who will move on to the next round. The final round is called the "championship game" and it's the biggest game of them all. The two best teams play against each other to try and win the championship title.
In the end, the team that wins the most games and scores the most points in the championship becomes the national collegiate women's ice hockey champion!
