The game starts with two of each player's pieces in the four central squares in a checkerboard fashion, with white at the top-left corner. Black moves first, then turns alternate. Place one piece on the board whereby a continuous horizontal, vertical, or diagonal straight line is created that has the current player's pieces at either end and all pieces in between are of the opposing player. Then, the opponent's pieces on said lines that exist are flipped over. Placing is mandatory - if no moves can be made, turn passes. The game automatically highlights available moves for the current player. The goal is to have the most points to win! Additional controls: drag with two fingers to rotate and zoom, and drag with three fingers to adjust the camera's tilt.
