The rules are simple. You take turns with another player to drop red or black pieces into the board. Pieces fall in from the top and slide down to stack up on top of each other. The goal is to get 4 of your pieces touching in a straight line (diagonals also count) before your opponent does. This is similar to Tic-Tac-Toe.

This is a 2 player game. Unless you have a split personality, you will need to install a second player (not included) somewhere near your Wii.
