You can pick up a Skunk Sweeper game in the Fun Stuff section of the W Shop or  by challenging a friend in the Clubhouse Games Room or at the Tournament Arena. There are skunks hidden under some of the tiles. Click on a tile. If there isn’t a skunk under it, a number tells you how many skunks are within the surrounding 8 squares. If you suspect a skunk is hiding under a tile, use the spacebar to mark the tile. Use the spacebar again to unmark it. To win the game, you need to uncover all the tiles that don’t have skunks under them.
