''Main Article: [[T-Spin Double Triple]]''
'''Imperial Cross''' (sometimes '''Imperial Crossing''') is a family of [[Twist#Twists with T (or T-Spin)|T-Spin]] setups in games using [[SRS]].
It uses SRS's spin triple twist plus an additional 180 degree rotation to make a [[Line clear#Hurdle_or_Split|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 [[Guideline compliant game differences|mid-2006 and later]], which [[Twist#Rewards for twists|do not recognize]] a [[Wall kick|kick]] twist as a T-Spin.
The basic setup is as follows:

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:
