Tetris DX (JU)

Tetris DX (JU) is a puzzle video game, first published by publisher Alexey Pajitnov in 1984. The game has seven types of blocks: I (vertical), J, L, O (square), S, T, Z (special images). We see each block of bricks is made up of 4 small squares put together, so they can combine together into one block easily. We can treat these blocks as rectangles of different sizes. Other shapes are created when rotating these basic blocks at angles of 90 degrees, 180 degrees, 270 degrees. The goal of the game is to move the falling bricks slowly down in a rectangle of 20 rows x 10 columns (on the screen). If there are bricks, they cannot move to that location. The player arranges blocks so that the puzzle fills a horizontal row to score points, and that horizontal line disappears. If the player allows the block to reach the top of the screen, they will lose.
