Bongcloud is an opener made by TuneWifi. This opener opens up an 8-1 stack with follow-ups or freestyle. | Requires T before S/Z and L/J before O (Opener is in W.I.P).

1ST BAG 1ST BAG - 2ND SITUATION

RESIDUE 1ST VARIANT | JO The simplest variant, as it offers the simplest solutions and least complex continuations in case the bags don't allow or may cause issues when setting up. Base Continuation 1: Most basic of them all. Doing this continuation requires you to hold the I piece. [ 3RD BAG ] You can either freestyle or do Yoshihiro. NOTE: If you get an early I piece, freestyle or set up a T-spin Triple and abandon 8-1 stacking. Continuation 2: This continuation gives you an Imperial Cross in exchange for a much lower build chance as it requires O before I. Continuation by: kamikazeyyyy While doing Imperial Cross, there's a high chance of doing STSD if you take the T-Spin Single on the 2nd T-spin. Continuation 2b: This is a better version of the Imp. Cross continuation. Continuation by: kamikazeyyyy Situation 1: Incase O piece is running a bit late. Continuation 3: Continuation by: binkien2009 13.33% 2ND BAG Upstack Fill-in 2ND VARIANT | ZLJ Let's feel a bit fancy with a T-Spin Triple instead of a T-Spin Double. Base with overhang Continuation 1: This continuation places I on the very left and S as an overhang (Requires to hold O).

[ 3RD BAG ]

It's nearly the same as the first variant in terms of continuations.

You can either do Yoshihiro or freestyle.

Situation 1:

Congruent ZLJ Shape

3RD VARIANT | ZO

Let's get even fancier with a Fin/Neo variant.

Continuation 1:

You can make a Fin using an L piece to abuse kick to make a T-Spin Double (Needs early L | Requires to hold Z).

Situation 1:

( WARNING: ABSTRACT THEORY )

Incase of early O, this can be used.

Continuation 2:

In this continuation, you make a Neo T-Spin which abuses kick to make a T-Spin Double Mini (In case of late L | Requires to hold J | Needs early J).

Using 2 pieces to create the notch.

Situation 1:

Either you want to do it for fun, to troll, or whatever you thought of trying to do this but ok.

Situation 2:

( WARNING: ABSTRACT THEORY )

In case of early O, this can be used.

4TH VARIANT | S4W

This is a S4W continuation.

Do note that it DOES not leave a 4 height well for a quad.

5TH VARIANT | TSJ

Two wasted T for an... LST??

Main stack

This stack is quite flexible, so turn some things a bit.

6TH VARIANT | TOZ

Another waste T for a DT? (possible TST S4W)

Variant by: binkien2009

[ 2ND BAG ]

[ 3RD BAG ]

TST S4W onwards.

Situation 1:

Use this in case of Late S.

7TH VARIANT | JTO

This variant is a TST Tower with a 66.67% Build chance.

Variant by: lukasdrakon

[ 2ND BAG ]

8TH VARIANT | SZ

Continuation 1:

Ways to make a tsd which do not cover the garbage hole

Continuation 2:

Imperial cross:

T-spin triple:

Unnamed:

You can make this setup that looks like imperial cross

Fake trinity:

You can take the TSD in most situations after the first Z. After the TSS you need to put an I on the left

Incomplete TST into a TSD:

T-spin triple donation:

Continuation 3:

You can either take a TSD or hold the T to build a fractal or imperial cross

MISC

CLOUDNINE VARIANT

If you don't like the idea of an 8-1 stack, this stack allows for 9-0 with a different 1st bag setup.

This allows for many donation opportunities.
