Quad is a puzzle game on www.flash-game.net in which your mission is to place the quads in lines. You will be given some block group in different shapes. You need to match them so that the quads will form a line vertically or horizontally. At this time, those quads will disappear, which means you have empty place to place new quads. If your board is stuffed by blocks, your game’s over. Try to hold on as long as you can. Have fun!
