Shipwreck Galleon Stacking

Under Construction

Shipwreck Galleon Stacking (or just SG Stacking for short) is an opener that was discovered by Winterfrost. The opener only needs S or Z to come before O in the first bag, assuming mirrors are used.

Path 1 (L before O)

This path requires L to come before O, and S to come before Z or after both J and Z. While it may seem like this path could cause you to wait for gravity on some bags, that is not the case as pieces can be soft dropped and slid under other pieces if need be, due to the even height differences on both sides of the board.

Alternatively, the 4th bag can be stacked like below if Z comes before O, but after S, leading to a clean 6-3 or 5-4 stack depending on which T orientation you choose. The L piece may need to be soft dropped into place if it comes after the Z piece, or you can just choose to freestyle if you don't want to deal with the inputs.

If S comes after both Z and J, you'll need to do this spin, which is just clockwise, soft drop, and clockwise again.

Path 2 (O before L)

This path requires O to come before L, and S to come before Z or after both J and Z.

You can choose to end the opener here, or continue into a DT Cannon.

The third bag can be stacked like below or freestyled if O comes before L.

Path 3 (All Bags)

If either of the two paths above cannot be built because of the order of the J, S, and Z pieces, then this path can be used instead. This path can also be used if you just want a safer option than the other two paths, as it can always be built one of these ways and doesn't require as much commitment. Only the first two setups are needed to cover all bags, but you can use the third setup if O comes before L or freestyle this bag for a cleaner stack or a higher chance to get another TST.

Perfect Clear Loops

If you get L before O, you will always be able to stack this loop.

This field has a 60.08% chance of achieving a 10 line perfect clear with 51 minimal solutions. If there is no perfect clear or you wish to complete a full loop, you can continue to a 14 line perfect clear.

This is the ideal build, having a 100% chance to achieve a 14l perfect clear.

If you get an unlucky queue and are unable to build the ideal path, there is a backup method that can always be stacked, leading to a 99.92% chance to achieve a 14l perfect clear.
