Get rid of pieces by putting five or more of the same color in one line (horizontally, vertically or diagonally) – at least with default settings, but the game is customizable.

In each turn, pick a piece on the board, and put it on an empty field. Pieces cannot jump (by default), i.e. there must be a clear path between the source and the destination field. After each move, new pieces appear on the board at random positions, except if the move made a line disappear. Each removed piece earns 1 point. If the board is full, the game ends.

Mouse control: click on the selected piece, and then click on the destination field.

Keyboard control: move the cursor by the arrow keys, and press Space or Enter to select the piece or the destination field.
