Quarto is published Gigamic.
There are 16 pieces, which have four different attributes: Height: large or small; Color: light or dark; Shape: square or circle; Solid or hollow.
To move: Players alternate turns choosing a piece which their opponent will place on the board.
To win: The first person to get four pieces in a row along any one of the dimensions: height, color, shape, solid or hollow.
Players take turns selecting their opponent's piece. Once your opponent has selected a piece, you must place it on the board in any open spot. The first person to get four in a row, either diagonally, horizontally or vertically wins. The catch is that the pieces that are lined up must share the same attributes.
- Board Size: Change the board dimensions to make it bigger or smaller
