Tetris (NES, Tengen)

Tet&#1103;is: The Soviet Mind Game is a pirate-original tetromino game for NES published by Tengen, the home video game division of Atari Games (now part of Midway). Much of the gameplay mechanics and the graphical style were lifted from the arcade Tetris by Atari Games. This Game Pak is rare because it was recalled after Andromeda Software, which at the time was Elorg's Western agent for the Tetris brand, lost the game console rights (see History).

The game gives line clearing bonuses only after completing each 30 lines (although deeper into gameplay some rounds require clearing 50 lines).
