Grim Grotto

Grim Grotto is a mid-game prophecy trimming setup that yields a T-Spin Triple. The order of the hang or trim are interchangeable.

The easiest way to remember is to look for the square shape (outlined). Make sure one uses the right piece though. If they use the wrong S or Z, it will create an "empty" S or Z-Spin Triple instead.


 * Compulsory: One must be careful of using the wrong piece.
