Tetris, also known as classic Tetris, is a puzzle video game for the Nintendo Entertainment System (NES) released in 1989, based on Tetris (1985) by Alexey Pajitnov. It is the first official console release of Tetris to have been developed and published by Nintendo. It was preceded by an official Tetris for the Family Computer in Japan in December 1988, and an unofficial Tetris by Tengen in North America in May 1989.
This version of Tetris has two modes of play: A-Type and B-Type. In A-Type play, the goal is to achieve the highest score. As lines are cleared, the level advances and increases the speed of the falling blocks. At the beginning of a B-Type game, the board starts with randomized obstacle blocks at the bottom of the field, and the goal is to clear 25 lines. In B-Type, the level remains constant, and the player chooses the height of the obstacle beforehand.
During play, the tetrominoes are chosen randomly. This leaves the possibility of extended periods with no long bar pieces, which are essential because Tetrises are worth more than clearing the equivalent amount of lines in singles, doubles, or triples. The next piece to fall is shown in a preview window next to the playfield. In a side panel, the game tracks how many of each tetromino has appeared in the game so far.
In A-Type, the level advances for every 10 lines cleared. Each successive level increases the points scored by line clears and changes the colors of the game pieces. All levels from 1 to 10 increase the game speed. After level 10, the game speed only increases on levels 13, 16, 19, and 29, at which point the speed no longer increases. On level 29, pieces fall at 1 grid cell every frame, which is too fast for almost all players, and it is thus called the "kill screen". The developers of the game never intended anyone to play past the killscreen, as the game does not properly display the level numbers past 29, but with modern speed techniques, skilled players can play past level 29.
When starting a game, the player can select a starting level from 0 to 9, but if the A button is held on the controller when selecting a level, 10 additional levels are added, raising the starting options to 0 to 19. When starting on a later level, the level is not supposed to advance until as many lines have been cleared as it would have taken to advance from level 0 to the starting level. Due to a bug, the levels will begin advancing earlier than intended when starting on level 10 or higher.
Saint Basil's Cathedral appears in the title screen and ending, alluding to the Soviet origin of Tetris.
At the end of an A-Type game, a substantial score yields an animated ending of a rocket launch in front of Saint Basil's Cathedral. The size of the rocket depends on the score, ranging from a bottle rocket to the Buran spaceplane. In the best ending, a UFO appears on the launch pad and the cathedral lifts off. After a high-level B-Type game, various Nintendo characters perform in front of the cathedral. After clearing around 1550 lines, the game is at risk of crashing due to inefficient multiplication operations. Crashing the game in this way is popularly considered "beating the game", a feat first achieved on 21 December 2023 by 13-year-old Willis Gibson, known by his online alias "Blue Scuti".
