Functionalities

• A piece with a randomized color and type is generated periodically and it moves down the playing area. User can control the orientation and position of the piece using arrow keys until the current piece reaches the bottom of the playing board. At this point a new piece is generated.

• User cannot move or orient a piece in the following situations:

  • The piece tries to move out of the playing board area as a result of the user’s action
  • If there is another piece already blocking it’s movement

• Exceptions are thrown if the above cases are encountered. The error is caught and the playing board border turns red, indicating to the user that his move is invalid and prevents the piece from making that move.

• If the user is able to form a straight line with a set of pieces, the scoreboard is updated and the said line is deleted from the playing board.

• If any piece touches the top of the playing board and no straight line is formed, the game ends.

• ESC : End Game and Close Window
