Fig: Jigsaw 1st PC bag structure. Includes 2nd PC Recovery, which involves building residue matching a 2nd PC setup.

Setup

Jigsaw 1st PC setups marked with ⭐ have 100% combined build cover and 100% recovery rate into 100% 2nd PC setups.
You must learn (build + recovery, not all solves) these setups in order to always be able to loop using Jigsaw 1st PC.

Solve rates are for all solves, not just the recovery routes shown.

Organised solves

It is important to save good pieces for 2nd. Saved pieces are those not used in solve.
In general, 2nd PC has three categories based on parity:

• Has T 2nd - Good 2nd. 100%. Typically easy and good saves for 3rd/DPC.
• No T, even JL 2nd - Still good, but sometimes tricky 2nd. 100%. Typically difficult and slightly worse saves for 3rd/DPC.
• No T, odd JL 2nd - Bad 2nd. No 100%. Bad saves for 3rd/DPC. Avoid at all costs.

In short, try not to use T piece in the solve.

* Technically what is a good save may differ slightly based on whether you want to follow up with 3rd or DPC.

⭐ Jaws Jigsaw (Hold T)

Lower PC% than PCOSaw, but scores higher on average thanks to guaranteed TS0 (with chance of upgrade to TSD/TSS).

Good saves (into Has T 2nd):

7p Jigsaw

6p Jaws Jigsaw

Tricky saves (into No T, even JL 2nd):

6p Jaws Jigsaw

Bad saves (into No T, odd JL 2nd):

7p Jigsaw

Dupe saves (into Dupe 2nd):

6p Jaws Jigsaw

You can ignore the dupe solve. It barely adds any PC%. Build recovery instead.

⭐ PCOSaw (Hold J)

Higher PC% than Jaws Jigsaw, but scores lower on average because no spin.

Good saves (into Has T 2nd):

7p Jigsaw

6p PCOSaw

Tricky saves (into No T, even JL 2nd):

(none)

Bad saves (into No T, odd JL 2nd):

7p Jigsaw

6p PCOSaw

Dupe saves (into Dupe 2nd):

6p PCOSaw

You can ignore the dupe solve. It barely adds any PC%. Build recovery instead.

🩹 Jigsaw Recovery

Jigsaw Bag 1

It is always possible to build this residue or its mirror.

Jigsaw Bag 2 Recovery - Tub + Vertical I (1)

100% build rate with 1 minimal. Better saves but has rare forced save I queues.

Hold I if you can, you will be able to choose between setups. This is possible when S isn't last of IOS.

Tub + Vertical I 2nd (1)

Jigsaw Bag 2 Recovery - Tub + Horizontal I (2)

100% build rate with 2 minimals. Easier solves and guaranteed save O/S/Z, but lower save O. Also skims might be more difficult to see.

Hold I if you can, you will be able to choose between setups. This is possible when S isn't last of IOS.

First build minimal can also place I horizontal 1 column from the wall, sometimes allowing save O or Tet solve when it otherwise wouldn't be possible.

Tub + Horizontal I 2nd (2)
