Tetris: Kiwame Michi

Tetris Kiwamemichi is a Tetris game for the Sega Naomi arcade platform and the PlayStation 2.

Tetris Kiwamemichi features the standard Guideline ruleset for gameplay. However, there is also a 750ms delay between a piece spawning and said piece speeding up to the current gravity value, thus making it easier to maneuver a tetromino at 20G.

Two level systems are used in-game:

Arcade – the level increases every piece drop or line clear, similar to the Grand Master series. This is the default system in the arcade version, and is interchangeable with the Home system in the PlayStation 2 version.
Home – the level increases every 10 lines cleared. This is the default system in the PlayStation 2 version.
