The
object of this
game is to drop
pentominoes onto a square board so as to form
complete lines. When a
line is formed, all the pieces contributing to it
disappear and you get
points. You may also get
bonus balls, which allow you to
rotate the pieces or
remove pieces from the board.
Various features will appear on the board during the game, and special things will happen if you surround them with pieces. The nicest ones are the medal, which completely clears the board, and the clock, which stops new pieces from appearing for a while. The nastiest one is the garbage can. Until you get rid of it by surrounding it or using a medal, a dirt patch will appear every time you make a line. You can't place pieces on dirt patches, so they interfere with making lines.
