The purpose of the game is to collect as many points as possible. You get points any time you link 5 or more pieces of the same colour in a line. To do this, you can move the pieces around the 9x9 square board. A piece to move cannot jump, so you can move it to an empty square only in case there is an open way to get there. You can move from square to square only horizontally or vertically, not diagonally, as illustrated below:

Valid move - the piece can go along the green line. | Invalid move - there is no way how to get to the target square.

The game starts with 5 pieces arranged randomly on the board. After every move the computer adds 3 more pieces on empty squares. Within one move you can move one piece over any number of adjanced squares. Click a piece to move it. The selected piece is emphasized. In case you changed your mind, click any other piece. To complete a move, click the target square. A sound of a beep indicates the intended move is invalid.

Join 5 or more pieces in a line to collect 5 or more points.

Good luck and enjoy playing. Let me know with any comments.
