All-Spin
After stacking in one of these ways you will have an S or O on hold.
These patterns use the second bag S/O to reliably create an Imperial Cross.
Use these when all else fails (requires use of 180 rotations)
Note if O comes early 3rd bag in either variation one can stack like so:
- Other ways to resolve patterns:
Imperial Cross:
STSD:
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.
- If the opportunity presents itself one can Z-Spin Single into Fin TSD for style points
This is highly freestyle but will usually require I>J/L for the Fin overhang
Zipper
Congruent shapes which use both S/Z delay the attack to the third bag.
This can be resolved like so, or upgraded into another Triple Double Attack.
