Tetris 64 is a game that was released in Japan for the Nintendo 64. It included a "bio-sensor" that measured the player's heart rate, for use in the Bio Tetris mode, and was the only game for the Nintendo 64 to use the sensor.
Tetris
The standard mode. The player can choose one of the three gameplay types originally from Tetris 2 + Bombliss.
- A-Type: The regular marathon mode. The player can start from levels 0 to 30. Level increases every 10 lines.
- B-Type: A stage mode. Each level has 6 heights (0-5, corresponding to 0, 3, 6, 8, 10, 12 lines of garbage). Clearing 25 lines will pass the stage, causing the player to advance a height. Clearing height 5 will advance the level.
- C-Type: Garbage mode. At certain intervals, garbage will rise from the bottom of the field. Gameplay is mostly the same as A-Type.
Giga Tetris
Giga Tetris sometimes gives the player giant pieces. When a line is made involving a giant piece, instead of clearing it will split into vertical dominoes. The dominoes will disappear if involved in a line clear. The mode also has cascade gravity.
Playfield width can be adjusted (options are 8, 10, 12, 14, 16, 18, 20).
Bio Tetris
Bio Tetris is based around measuring the player's heart rate using the Bio Sensor. Based on the player's heart rate, the game will give out harder or easier pieces.
The heart indicator changes colour depending on the player's heart rate, with red representing the slowest rate, followed by yellow, green and blue.
More specifically, the extra pieces are divided into two groups as follows:
| Group

Bio Tetris is the only mode where 5-line clears are possible. Performing one will add 1,800 points to the player's score.
Options
The game includes a surprising number of options, particularly regarding rotation. Moreover, enabling some of these options allows the player to perform unique spin moves, including an O-Spin (though these are not recognised by the game).
