• O save

Use these when all else fails

• S save

• The STSD pattern can be resolved with many piece combinations:

Alternatively one can opt for a t-spin single in trinity to form either a t-spin or z-spin next. (See the Trinity hard drop page TSD Declined or Approved?)

• Listed are some congruent shapes that result in the same Triple Double Attack.

Zipper

Congruent shapes which use both S/Z delay the attack to the third bag.
