This is a version of the puzzle game Lines by Oleg Demin. Slide pieces around to try and form lines of five or more tiles horizontally, vertically or diagonally. When you form one or more lines, the tiles will disappear. If you fail to form any line after making a move, three new tiles will appear. "?" tiles are wildcards, and match any tile. They only exist when playing on easy.
