Imperial Cross

From TetrisWiki
Jump to navigation Jump to search

Imperial Cross (sometimes Imperial Crossing) is a family of T-Spin setups in games using SRS. It uses SRS's spin triple twist plus an additional 180 degree rotation to make a hurdle double, followed by a standard T-Spin double.

Because of the 180 degree rotation after the spin triple twist, it works even in games from mid-2006 and later, which do not recognize a kick twist as a T-Spin.

The basic setup is as follows:

Cross Opening

In games that only reward no-kick T-Spin Single and Double like Tetris Evolution, Imperial Cross becomes a useful opening.
