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.


Standard Tetris with 3 modes, based on those in Tetris 2 + Bombliss:

  • A-Type is a standard marathon mode. The player can start from levels 0 to 30. Level increases every 10 lines.
  • B-Type is 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 is similar to A-Type, but garbage will rise from the bottom at certain intervals.

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 Pieces
A Group
B Group ...

Scoring is the same as in normal Tetris except that 5-line clears are worth 2400.


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).
