3. ACKNOWLEDGEMENT I extended my thanks to Project Supervisor MS. RASHI RASTOGI for giving me the motivation and guidance to complete this project. I deeply indebted to my project for the initial idea of the project and for all the guidance and encouragement he gave in the subsequent months. Lastly, I would like to thanks the entire staff of the MCA Department and our college for their support and co-operation in the completion of the project. Name: Ujjwal Upadhayay

4. introduction Tetris is a classic tile-matching puzzle video game originally designed and programmed by Alexey Pajitnov in the Soviet Union. The game was first released on June 6, 1984, and has since become one of the most recognizable and influential video games of all time. The name "Tetris" derives from the Greek numerical prefix "tetra-" (meaning "four") and "tennis," Pajitnov's favorite sport, reflecting the game's use of tetrominoes, geometric shapes composed of four square blocks each.

5. How Tetris is Played In Tetris, players must strategically rotate and place falling tetrominoes into a rectangular playfield (the "well" or "matrix"). The goal is to fill horizontal lines with blocks without any gaps. When a line is completely filled, it disappears, and any blocks above it move down. Players score points for each completed line, and the game continues to speed up, increasing the challenge. The game ends when the stack of blocks reaches the top of the playfield, preventing further tetrominoes from entering. 5

6. Key Elements of Tetris 6 Tetrominoes : The game's primary building blocks, each consisting of four squares in seven different configurations (I, J, L, O, S, T, Z). Playfield : The grid where tetrominoes fall, typically 10 blocks wide and 20 blocks high. Rotation and Movement : Players can rotate tetrominoes and move them left or right as they fall. They can also "soft drop" (speed up the fall) or "hard drop" (immediately place the tetromino at the bottom). Clearing Lines : Completing one or more horizontal lines causes them to disappear, making room for new blocks. Clearing multiple lines at once scores more points. Scoring : Points are awarded based on the number of lines cleared simultaneously and the level of difficulty. Increasing Difficulty : As the game progresses, tetrominoes fall faster, increasing the difficulty and requiring quicker decision-making.

7. Gameplay 7 Tetris  is primarily composed of a field of play in which pieces of different geometric forms, called " tetrominoes ", descend from the top of the field. During this descent, the player can move the pieces laterally and rotate them until they touch the bottom of the field or land on a piece that had been placed before it. [  The player can neither slow down the falling pieces nor stop them, but can accelerate them, in most versions. The objective of the game is to use the pieces to create as many complete horizontal lines of blocks as possible. When a line is completed, it disappears, and the blocks placed above fall one rank. Completing lines grants points, and accumulating a certain number of points or cleared lines moves the player up a level, which increases the number of points granted per completed line.

8. In most versions, the speed of the falling pieces increases with each level, leaving the player with less time to think about the placement. The player can clear multiple lines at once, which can earn bonus points in some versions. It is possible to complete up to four lines simultaneously with the use of the I-shaped tetromino; this move is called a "Tetris", and along with the fact that its seven different pieces (tetrominoes) are made up of 4 squares, is the basis of the game's title.   If the player cannot make the blocks disappear quickly enough, the field will start to fill; when the pieces reach the top of the field and prevent the arrival of additional pieces, the game ends. At the end of each game, the player receives a score based on the number of lines that have been completed. The game never ends with the player's victory, as the player can complete only as many lines as possible before an inevitable loss. [2] Since 1996, the Tetris Company has internally defined specifications and guidelines to which publishers must adhere to be granted a license to  Tetris . The contents of these guidelines establish elements such as the correspondence of buttons and actions, the size of the field of play, and the system of rotation. 8

9. Game pieces The pieces on which the game of  Tetris  is based around are called "tetrominoes". Pajitnov's original version for the  electronica . computer used green brackets to represent the blocks that make up tetrominoes. Versions of  Tetris  on the original Game Boy/Game Boy Color and on most dedicated handheld games use black-and-white or  grayscale. graphics, but most popular versions use a separate color for each distinct shape. Prior to the Tetris Company's standardization in the early 2000s, those colors varied widely from implementation to implementation. 9 ( All seven  tetrominoes  using the standard color scheme)

10. Scoring The scoring formula for the majority of  Tetris  products is built on the idea that more difficult line clears should be awarded more points. For example, a single line clear in  Tetris Zone  is worth 100 points, clearing four lines at once (known as a  Tetris ) is worth 800, while each subsequent back-to-back  Tetris  is worth 1,200. In conjunction, players can be awarded combos that exist in certain games which reward multiple line clears in quick succession. The exact conditions for triggering combos, and the amount of importance assigned to them, vary from game to game. 10 Nearly all  Tetris  games allow the player to press a button to increase the speed of the current piece's descent or cause the piece to drop and lock into place immediately, known as a "soft drop" and a "hard drop", respectively. While performing a soft drop, the player can also stop the piece's increased speed by releasing the button before the piece settles into place. Some games allow only one of either soft drop or hard drop; others have separate buttons for each. Many games award a number of points based on the height that the piece fell before locking, so using the hard drop generally awards more points.

11. GETTING STARTED Press the START button to begin a new game. You will see the Game Mode screen. To scroll through the game modes, press the SOFT DROP BUTTON. There are four game modes: Tetris Marathon (Game One), Tetris Ultra (Game Two), Tetris 40 Lines (Game Three), and Tetris Dig (Game Four). Before selecting a GAME MODE, you can also select a GAME LEVEL from which to start. There are ten game levels, each increasing in difficulty. When in SET-UP MODE, each level is represented by a colored, vertical line across the bottom of the screen. Press the RIGHT and LEFT DIRECTION buttons to increase or decrease the skill level. When you have selected the desired game mode and game level, press the START button to begin your game. TETRIMINO CONTROL As the Tetriminos fall, you will need to rotate or slide them to fit into the lines below. You can move a Tetrimino to the left or to the right as it is falling by pressing the LEFT AND RIGHT DIRECTIONAL BUTTONS. To rotate a Tetrimino clockwise, press ROTATION BUTTON 2 until the Tetrimino is in the desired position. To rotate a Tetrimino counter-clockwise, press ROTATION BUTTON 1 until the Tetrimino is in the desired position. A Tetrimino will come to rest after it has come into contact with the bottom of the matrix or the blocks beneath it, you can slide it to the left or right before “LOCK DOWN’’. rules

12. HARD DROP To instantly drop and lock a Tetrimino into place, use the HARD DROP BUTTON. The Tetrimino falls into place and immediately “LOCKS DOWN.” SOFT DROP To accelerate the speed at which a Tetrimino falls, press the SOFT DROP BUTTON. Until it’s in contact with the bottom blocks, you have half a second to move the Tetrimino before it “LOCKS DOWN.” T-Spin A T-Spin is a special rotation of the T-shaped Tetrimino into a T-Slot (an opening in the shape of a “T”). To perform the move, a T-shaped Tetrimino must have landed on its side and not locked down. Once the Tetrimino is on its side, spin it clockwise or counter clockwise using the rotation buttons, dropping the Tetrimino into the T-Slot. PAUSING THE GAME To “pause” during game play, press the PAUSE button. Press this button again to return to the game in progress . GAME OVER If you cannot complete a line, the blocks will eventually stack up and rise to the top of the matrix (“BLOCKING OUT”) and the game will end. The words “Game Over” will scroll across the screen. At the end of the game, the SCORE INDICATOR will display your line score and the high score.
