Fig: Gamushiro bag structure. Includes DPC Recovery, which involves placing the extra piece in a specific spot compatible with a DPC setup.

Gamushiro setups marked with ⭐ have 100% combined build cover and 100% recovery rate into 100% DPC setups.
You must learn these setups in order to always be able to loop using Gamushiro.

Gamushiro Bag 1

Gamushiro (Hold L): 100.00% with mirror (66.67% without mirror).

Gamushiro Bag 2 (Hold L)

Technically Gamushiro Default isn't necessary. However, it's included because it's better than Gamushiro Alt 1 and Gamushiro Alt 2, as well as good to know in general.
Gamushiro Default is 100% build rate if you forgo TST.

Gamushiro Alt 3: Gravity wait can be avoided by utilising terrain:

Fig: Gamushiro Alt 3 gravity wait avoid.

Gamushiro Alt 2: L can be spun in using 180 after S has been placed:

Fig: Gamushiro Alt 2 L 180.

Gamushiro PC: If you can place 4p/5p like this (57.14% chance),

there's another solve leading into Tub 2nd with alternate T placement, bringing Gamushiro PC% up to 25.95% when the 4p/5p is buildable:

Furthermore, if you can place 4p/5p like this (61.90% chance),

there are two additional solves leading into Tub 2nd with alternate Z placements, bringing Gamushiro PC% up to 33.57% when the 4p/5p is buildable:

Many other PC solves from various 4p/5p exist. It is recommended not to sacrifice speed for PC.

Note that there's another solve possible from 6p, but it is not recommended because it leads into a bad 2nd and scores less on average than Gamushiro would normally:

⭐ Gamushiro Alt 3 Solve

⭐🩹 Gamushiro Alt 3 Full Recovery (4)

You can choose either of the O recoveries builds to cover all fail queues together with the other two recoveries.

⭐ Gamushiro Alt 3 Minimals (16)

Gamushiro Alt 3 Extra (3)

Many solves are work the same way as SDPC Alt solves:

If you can place ILO like this, the remaining field is 100% for any piece order:

Space divisions make finding solves simpler:

When T comes in the middle of the bag, it's sometimes possible to get the spin after skimming.
Skim in a way that creates a hole ready for the O piece to be placed last on top of the T slot.
Hold O until T has been placed:

When T comes too late, you'll often need to skim the top rows first.
Skim in a way that blocks off the T slot, ready for T to be placed last once the top rows have been resolved.
Here O cannot be used to resolve the space above the T slot because it would fall through.
Place O on the other side instead:

Gamushiro Default Useful (3)

All spin solves + useful solves give 91.75% PC%.
Without greedy save L TSS that's 89.09% with 58.69% TSS+.
You can build recovery instead of looking for a complicated solves.

Following useful L-spin is possible without 180:

Fig: Gamushiro Default L-spin solve.

This common solve usually starts by JLO skim and T-spin, but this exotic order requiring a spin sequence also exists for the same solve. Possible without 180:

There's this funny spin save L TSD utilising the TST kick:

Gamushiro Default can sometimes be upgraded to Gamushiro Alt 2/Gamushiro Alt 4 potential TSS+Tet solve if you can spot a good queue:

⭐ Gamushiro Alt 1 Solve

⭐🩹 Gamushiro Alt 1 Complementary Recovery (2)

To be used in combination with Minimals. These recoveries cover all the fail queues.

Gamushiro Alt 1 Extra (1)

Many solves are just congruents of Gamushiro Default solves:

Space divisions make finding solves simpler:

Minimals respecting above space divisions bring together with Recovery have 99.96% build rate with 59.52% TSS+ PC chance and avoiding J DPC.
When you get the fail queue ([JO]!TZISL), do a greedy TSS save L solve or use the save S recovery below.
PC% is only 88.37% without using the other minimals but it's enough for basic looping.

(🩹 Gamushiro Alt 1 Full Recovery (2))

A full recovery route with 2 minimals exists.
While you never need the first one, it's good to know to avoid bad saves/difficult solves or if you make a mistake.

If you can do the T-spin early and hold, LS, you can choose between Gamushiro Alt 2 and Gamushiro Alt 4:

This can be used to increase PC% as well as scoring.

Watch out mostly for early/late J/L.
PC% and TSD% is greater with horizontal box:

Whereas TSS+Tet% can be achieved with vertical box (careful not to miss PC in the process):

Gamushiro PC Solve

Tub + Vertical I 2nd

Better saves than Tub + Horizontal I 2nd, but harder to solve.

Minimals (7)

Extra (7)

Extra Save O (7)

Rather than memorising minimals, it's easier to just solve box using a larger number of simple solves.
The last 180 minimal is the only one you need to memorise.

Tub + Vertical I has 0.24% forced save I. These queues are OSZ<I<JL<T. This solve requires 180:

Fig: Tub + Vertical I forced save I minimal 180 spin.

Forced save I can be avoided by placing O at the wall:

Sometimes it's possible to get extra Tet with 180:

Fig: Tub + Vertical I Tet 180 spin.

🩹 Tub + Vertical I on the wrong side Recovery

If you build Tub + Vertical I on the wrong side, those 0.24% forced save I queues actually become fail queues. In that case, use this recovery:

Tub + Horizontal I 2nd

Simpler to solve than Tub + Vertical I 2nd, but worse saves.
