$\}$ I already have all of my shapes and am able to randomize them. But I am having a lot of trouble with Instructions $($Views$)$

This package is simply going to contain the GUI for the game. $$You are going to need to add to my GUI a place for the score and also a preview of the next block to be dropped.The controllers package is where you need to implement the logic for the game. $$You can break up the logic into as many or as few classes as you see fit, but your package must handle the following:

Detecting when a row $($or rows$)$ have been filled and shifting down the blocks from the rows above

Scoring the game

Detecting when the game is over

Randomly choosing the next piece to drop

Detecting when a piece has fallen as far as it possibly can $($I have started this for you, you will need to finish it$)$ Thank you
