Wongsz spin
Wong sz spin
2 bag SZ spin triple pattern into TSD.
First bag has a (theorised) 100% build rate mirrored, 180 spins are essential for piece order. Without mirrored some bags with an early combination of T, I, Z may not be possible.
Opener is best suited for all-spin. (I made this for fun and list continuations I think are interesting)
Castletop
If T and I are placed, one can begin stacking imperial Cross early (S/O piece).
- Left - O save | Right - S save
Cleanest of the continuations- stacks shown are optimised to continue with freestyle trinity stacking, the imperial cross shape can be made in other ways.
The J piece can always 180 into place.
Third bag O is best placed on either side of the well to allow for s/z overhangs.
- O save (O from 2nd bag placed early)
An interesting stack (not necessarily recommended) one must 180 spin as shown to complete the TSD.
- If O comes early 3rd bag and cannot be placed on either side of the well, one can create the following stack.
- S save (S from 2nd bag placed early)
The Trinity/STSD shape can be useful for all spin.
Trinity stacking itself is not recommended as completing the first trinity without imperial cross has lower chances before the next T piece. Overhang depends on bag.
In all-spin using the T to make the overhang isn't fatal (see below). Building Trinity is freestyle but easier to stack from S save.
Common stacks include:
- The STSD shape is good for all spin as it allows a variety of different spins. This is why using a T to make the overhang is forgiving.
- 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?)
Flat top
This variation offers stacks when Castletop does not work (most notably early S- diagram 3/4).
If possible it's generally better to use the T from the first bag to help stack the overhang first. It can be made in 4 ways:
TSD donation
This continuation has a 100% build rate - the J O L stack can be vertically flipped depending on the bag, the floating TSD can be built before initiating the S/Z spin triple or substituted for an S spin double to avoid soft drop if the piece order allows for it.
One can make a TSD or produce an STSD after a TSS and skim (one can maintain b2b with an L spin if you can TSS early, even with S placed), the TSD is recommended:
The Z overhang can easily be made into a trinity (freestyle shown, not necessarily recommended)
All-spin fin
Best used in all-spin for b2b bonus. Can be made from either variations requiring an early I. See Polymer T-Spins to execute the tsd properly. Most fin setups can switch J and L, stack freestyle for a centre well. Z is required to fill the cavity.
A fractal can be made on all (except S overhang) stacks, this results in a high stack. The fractal can be amended with an L spin.
- Flat Top (wastes T not recommended- can easily be avoided by using one of the other four stacks)
Double Spin
(Work in progress)- This may be a viable continuation instead of a last resort though it's not clear yet.
If one encounters an early combination of Z and T in their second bag they can opt for an S spin double instead leading to a freestyle 5-4 stack. Usually the T overhang leads to cleaner residue, it's preferable to maintain a level centre for easier follow ups.
It's generally easy to freestyle the left well with 2 or 3 minos, one example being I and T from castletop or a combination of J/L and O. After the S spin is complete it's usually easiest to follow up with a tetris. T-spins are slightly harder to make unless the residue is clean enough.
An interesting stack: left well can be freestyled, L/J can substitute the O.
Though it looks cool stacked if possible you shouldn't waste Z but instead carry the spins out individually like so:
