Blue Dire Mondo

There are also subspecies, which are summarized on one page.

Blue Dire Mondo
Blue Dire Mondo is one of those openers that can get 8-lines PC; the first bag can be stacked on only one side, TSD is possible on the second bag, and it can always be done up to the third PC. The opener was invented by cerulean on January 17, 2022 Japan time.

1st bag
Always stackable; 6 different ways to stack. No left-right flipping is required, just one side.

2nd bag
TSD is always possible; O-piece, J-piece, and L-piece are interchangeable in placement.

3rd bag(PC)
PC rate is 100.00%, TSSPC rate is 26.94%, TSDPC rate is 26.07%, 16 filter solutions.

derivation to 14-lines PC
This opener alone can theoretically create an infinite PC loop.

3rd bag
Always TSD.

4th bag
Always TSD after Double.

5th bag(PC)
PC rate is 100.00%, TSSPC rate is 18.89%, TSDPC rate is 16.19%, 9 filter solutions.

subspecies opener (no name)
It can always be the same as Blue Dire Mondo, or it can always be a different shape. the first bag can always be stacked on one side as well. This opener was also invented by cerulean on April 24, 2022 Japan time.

1st bag
Always stackable; 6 different ways to stack. No left-right flipping is required, just one side.

2nd bag
Both routes A and B can always be stacked to produce a TSD; route A has the same shape as Blue Dire Mondo, so I omit the explanation from this point on.

S-piece, J-piece, and L-piece are interchangeable in placement. O-piece, J-piece, and L-piece are interchangeable in placement.

3rd bag(PC)

 * 2nd bag B route(PC rate is 100.00%, TSSPC rate is 11.47%, TSDPC rate is 11.47%, 16 filter solutions.)

derivation to 14-lines PC
This opener alone can theoretically create an infinite PC loop.
