Lines of Action
Move by the count of the line and link all your checkers into one group.
How to play Lines of Action
You are Black and move first. Click one of your checkers to see its legal squares, then click a highlighted square to move. A piece always moves in a straight line — horizontally, vertically, or diagonally — exactly as many squares as there are pieces of either colour standing on that whole line. You may leap over your own pieces but never over an enemy, and you land on an empty square or capture an enemy there. Your goal is to be first to gather all of your pieces into a single connected group (touching sideways, up-down, or diagonally). Tap the 2P button to play a friend instead of the computer.
