Hint: Discovering codes:

While playing the game, when you get a goal you will see short FMV sequence afterwards. In one clip, you can see the player go over to the side of the rink and see the crowd. At the top you will see some people holding and flipping signs. Look at them closely and you will notice that they form codes, such as "N N N Down." Press X, Y, and B followed by the D-pad direction at the vs. screen to activate the code.

Hint: Easy credits:

Select the All-Star difficulty setting and start a game. Switch the difficulty to Rookie during the game. You will get the credits from playing an All-Star difficulty for playing the CPU at the Rookie difficulty.

Hint: More skill competition levels:

Successfully complete all of the skills in a competition level to unlock an additional level

Hint: Get faceoffs:

Faceoffs are somewhat like a Paper, Rock, Scissors game, where one move beats another. In the game, A is similar to Paper, B is similar to Rock, and Square is similar to Scissors -- A beats B, B beats X, and X beats A. You can tell what the other person does by watching their stick. When they press A, their stick will twitch. When they press B, their hand will come off of the back of the stick. When they press X, they will hold their stick up high.
