Tetris, developed by Bullet-Proof Software, was the first licensed game to be released commercially in Japan. It was released on most of the common home computers from the era.

A Famicom port was released in December, 1988.

Gameplay

The game is split into six rounds of ten stages. Drop speed increases with each stage, while each round starts with higher amounts of garbage. Each stage is completed after 25 lines are cleared, after which the playfield is reset.

The player has three lives. Topping out will cost the player a life.

Scoring

Line clears are scored as follows:

Line clear	Points
1 (single)	40
2 (double)	100
3 (triple)	300
4 (tetris)	1200

If the piece was hard dropped, an amount equal to the number of rows covered by the hard drop plus 1 is added. Otherwise, no score for dropping is added.

Points are only totalled up either after the stage is cleared or if a life is lost.
