Tetris (Nintendo Entertainment System, 1989)

Tetris (or Classic Tetris) is a puzzle video game for the Nintendo Entertainment System (NES) released in 1989, based on Tetris (1984) by Alexey Pajitnov. 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 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. Condition: Loose cartridge, cleaned, and tested working.
