Flash 3DX is an interesting skill game on www.flash-games.net for free. The goal for you is to fill each row and remove it. In this game, the window on the left side will tell you the shape of the next piles. Press the up arrow key to change it if you need. Then use left and right arrow keys to adjust the appropriate position to place it. When a row is filled by piles, it will be removed. Try to keep the piles not blocking too high, because that would bring you troubles to arrange your next placement. Come on and challenge your record!
