Snowball Showdown

From MHWiki

The Snowball Showdown mini-game is similar to the Battleship game, and is accessed as a pop-up window from the Heads-up Display by clicking on the snowball icon on the left. For each Throwable Snowball a hunter collects, they have a chance to throw at one of 66 squares (6 rows of 11 columns) that have not yet been revealed.

4 of the following shapes will be hidden on the board (although they may be oriented differently on the board than how they appear below the board):
