Video of an open-source TetrisTetris is primarily composed of a field of play in which pieces of different geometric forms, called ', 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 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 moves the player up a level, which increases the number of points granted per completed line.
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 tetrimino; this move is called a 'Tetris', and is the basis of the game's title. If the player cannot make the blocks disappear quickly enough, the field will start to fill, and 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; the player can only complete as much lines as possible before an inevitable loss. Since 1996, The Tetris Company has internally defined specifications and guidelines that publishers must adhere to in order to be granted a license to Tetris. The contents of these guidelines establish such elements as the correspondence of buttons and actions, the size of the field of play, the system of rotation, and others. Game pieces. All seven tetriminos using the standard color schemeThe pieces on which the game of Tetris is based around are called 'tetriminos'.
Pajitnov's original version for the computer used green brackets to represent the blocks that make up tetriminos. Versions of Tetris on the original Game Boy/Game Boy Color and on most dedicated handheld games use 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.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. 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 only allow either soft drop or hard drop; others have separate buttons for both. 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.Easy spin dispute Although not the first Tetris game to feature a new kind of Tetris, 'easy spin' (see ), also called 'infinite spin' by critics, was the first game to fall under major criticisms for it.
Easy spin refers to the property of a Tetromino to stop falling for a moment after left or right movement or rotation, effectively allowing someone to suspend the Tetromino while thinking on where to place it. This feature has been implemented into 's official guideline. This type of play differs from traditional Tetris because it takes away the pressure of higher level speed. Some reviewers went so far as to say that this mechanism broke the game. The goal in Tetris Worlds, however, is to complete a certain number of lines as fast as possible, so the ability to hold off a piece's placement will not make achieving that goal any faster. Later, GameSpot received 'easy spin' more openly, saying that 'the infinite spin issue honestly really affects only a few of the single-player gameplay modes in Tetris DS, because any competitive mode requires you to lay down pieces as quickly as humanly possible.' In response to the issue, stated in an interview that infinite spin was an intentional part of the game design, allowing novice players to expend some of their available scoring time to decide on the best placement of a piece.
Rogers observed that 'gratuitous spinning' does not occur in competitive play, as expert players do not require much time to think about where a piece should be placed. A limitation has been placed on infinite lock delay in later games of the franchise, where after a certain amount of inputs i.e.: rotations and movements, the piece will instantly lock itself. This is defaulted to 15 inputs. The version designed by Spectrum Holobyte contained Russia-related images (Amiga version screenshot, 1988)Tetris was created in June 1984 by, an researcher working for the at Computer Center in Moscow. Tasked with testing the capabilities of new hardware, Pajitnov would do so by writing simple games for them. He initially considered creating a game around, which featured in puzzle games that he had enjoyed as a child, but felt that it might have been too complicated with twelve different shape variations, so the concept switched to, of which there are seven variants. The on which he was working had only a text-based display, so the tetrominoes were formed of letter characters.
Realizing that completed lines resulted in the screen filling up quickly, Pajitnov decided to delete them, creating a key part of Tetris gameplay.Pajitnov's game proved popular with his colleagues. Academy of Sciences co-workers Dmitry Pavlovsky and ported the game to the. Gerasimov reports that Pajitnov chose the name Tetris as 'a combination of ' and 'tennis'. From there, the PC game became popular and began spreading around Moscow.
Gerasimov removed his 1988 version of the game from his website in October 2003, in response to a demand from counsel for The Tetris Company. He resumed making it available in August 2006.The PC version made its way to, Hungary, where it was ported to various platforms and was 'discovered' by British software house Andromeda. They attempted to contact Pajitnov to secure the rights for the PC version, but before the deal was firmly settled, they had already sold the rights to. After failing to settle the deal with Pajitnov, Andromeda attempted to license it from the Hungarian programmers instead.Meanwhile, before any legal rights were settled, the Spectrum HoloByte IBM PC version of Tetris, which contained background graphics featuring Russian scenes, was released in the in 1987.
The game's popularity was tremendous; called the game 'deceptively simple and insidiously addictive'.The details of the licensing issues were uncertain by this point, but in 1987 Andromeda managed to obtain copyright licensing for the IBM PC and any other home computer system. Their release in 1988 has a 26-minute soundtrack composed by game musician Wally Beben.For and, two different versions by (1987) and Spectrum HoloByte (1988) became available. The Mirrorsoft version did not feature any background graphics, while Spectrum HoloByte's version was similar to their PC version and contained the similar images (it was also distributed by in some regions). The games were sold as budget titles due to the game's simplicity. Spectrum's package contained three diskettes with three different versions of the game, for the and on separate and 5.25 in (133 mm) diskettes, and for the on a 3.5 in (89 mm) diskette, none of which was copy-protected: the included documentation specifically charged the purchaser on their honor to not give away or copy the extra diskettes.
Unsure of how to publish his game and fearful of the response of the Soviet regime if he did so, Pajitnov took the opportunity offered by and gave the rights to the Soviet government for ten years. In 1988, the Soviet government began to market the rights to Tetris, following a promotional trip to the country by Gerald Hicks, the one-time United States champion of the gamethrough an organization called, or 'Elorg' for short. At this time, Elorg had still not been paid by Andromeda, but Andromeda was licensing and sub-licensing the rights to the game. A different version of Tetris was originally released in late 1988 by (BPS) for several Japanese home computers as well as the and the in, predating Nintendo's version. An unlicensed arcade version was released in, as well as an unlicensed (titled Super Tetris (슈퍼 테트리스 Syupeo Teteuriseu)).Nintendo. Main articles: andBy 1989, half a dozen different companies claimed rights to create and distribute the Tetris software for home computers, game consoles and handheld systems. Elorg, meanwhile, held that none of the companies were legally entitled to produce an version, and signed those rights over to, while it signed non-Japanese console and handheld rights over to.

Rogers later said, ' Tetris made Game Boy and Game Boy made Tetris.'

It is expected for release in 2019. Variations.
A running Tetris (2006)Tetris has been subject to many changes throughout releases since the 1980s. Newer Tetris games have emphasized pace rather than endurance. Older releases such as Game Boy or NES Tetris offer records according to points. Since the meter for points is restricted to a specific number of digits, these games' records can be 'maxed out' by an experienced player. The next big Game Boy release after Tetris, Tetris DX, in marathon mode—comparable to mode A in previous releases—allowed an additional digit for the point meter. Even so, players still maxed it to 9,999,999 points after hours of play.
For, world record competitors have spent over 12 hours playing the same game. In Tetris DX and The New Tetris, the new modes sprint and ultra were added. These modes require the player to act under a timer, either to gain the most lines or points in that time. Releases like Tetris Worlds removed point records. This particular game kept records by how fast a certain number of lines could be cleared depending on the level. Critics of Tetris Worlds said it was flawed by virtue of the ability of a piece to hover over the bottom for as long as a player needs.Many different modes of play have been added in recent years.
Modes appearing in more than one major release include classic marathon (game A), sprint (otherwise game B or 40 lines), ultra, square, and cascade.The field dimension of Tetris is perhaps the least deviated among releases: almost always 10 cells wide by 20 high. Some releases on handheld platforms with small screens have smaller fields; for example, the Tetris Jr. Has 8 by 12, and Tetris for Game Boy has 10 by 18.Traditionally, blocks spawn within the four most central columns and the two highest rows. The I Tetrimino occupies columns 4, 5, 6 and 7, the O Tetrimino occupies columns 5 and 6, and the remaining 5 Tetriminos occupy columns 4, 5 and 6 (or in some, especially older, versions, 5, 6 and 7). In some more recent games, pieces spawn above the visible playfield.In traditional games, a level-up would occur once every ten lines are cleared.
In some newer games such as Tetris Worlds, the number of lines required varies upon each new level. After a level-up, points awarded are increased and the blocks fall slightly faster. For example, NES Tetris operates at 60 frames per second.
At level 0, a piece falls one step every 48 frames, and at level 19, a piece falls one step every 2 frames. Level increments either terminate at a certain point (Game Boy Tetris tops off at level 20) or increase forever yet not in speed after a certain point. NES Tetris will level up in speed until level 29 (due to limitations of the game's engine, pieces are not capable of dropping faster than this), but tool-assisted emulation will show that the level indicator increases indefinitely—eventually leading to a glitch where the meter displays non-numeric characters. Modern games such as Tetris the Grand Master or Tetris Worlds, at their highest levels, opt to drop a piece more than one row per frame. Pieces will appear to reach the bottom as soon as they spawn.
As a result, these games have a delay that lets the player slide the piece on the bottom for a moment to help deal with an otherwise unplayable fall speed. In some games, the hover time is regenerated after a piece is moved or rotated.Soft drops were first implemented in Nintendo releases of Tetris so that pieces would be able to drop faster while not locking as to slide into gaps. The other option is hard dropping, which originated in early PC games such as Microsoft Tetris, a game developed by Dave Edson and bundled with. With hard dropping, a piece falls and locks in one frame. Newer Tetris games feature both options.
Some games have their locking roles reversed, with soft dropping making the pieces drop faster and locking down, and hard dropping making the pieces drop instantly but not lock.Single direction rotation is an older restriction that has since been ruled out in nearly every new official release by the favor of separate buttons for clockwise and one for counter clockwise rotation. In traditional games, the unsymmetrical vertical orientation I-, Z-, and S-pieces will fill the same columns for each clockwise and counter clockwise rotation. Some games vary this by allowing two possible column orientations: one for counter clockwise and one for clockwise rotations.
Double rotation—only seen in progressive clones such as Quadra and DTET—rotates the piece 180°.One of the features most appreciated by skilled players is wall kick or the ability to rotate the pieces even if these touch the left or right walls. In the NES version, for example, if a Z piece is 'vertically' aligned and falling touching the left wall, the player cannot rotate the piece, giving the impression that the rotate buttons are locked. In this situation, the player has to move the piece one position to the right before rotating it, losing precious time. Proper implementations of wall kick first appeared in the arcade version of Tetris by Atari Games.Piece preview allows a look at the next piece to enter the field. This feature has been implemented since the earliest games, though in those early games, having the preview turned on made the score increase more slowly.Variants.

Prolonged Tetris activity can also lead to more efficient brain activity during play. When first playing Tetris, brain function and activity increases, along with greater cerebral energy consumption, measured by metabolic rate. As Tetris players become more proficient, their brains show a reduced consumption of glucose, indicating more efficient brain activity for this task.
Moderate play of Tetris (half-an-hour a day for three months) boosts general cognitive functions such as 'critical thinking, reasoning, language and processing' and increases thickness.In January 2009, an Oxford University research group headed by Dr. Emily Holmes reported in that for healthy volunteers, playing Tetris soon after viewing traumatic material in the laboratory reduced the number of flashbacks to those scenes in the following week. They believe that the computer game may disrupt the memories that are retained of the sights and sounds witnessed at the time, and which are later re-experienced through involuntary, distressing flashbacks of that moment. The group hopes to develop this approach further as a potential intervention to reduce the flashbacks experienced in but emphasized that these are only preliminary results.Professor Jackie Andrade and Jon May, from 's Cognition Institute, and Ph.D.
