Glitter Brooch

The Glitter Brooch by Agent RO.

First Bag
There are 3 requirements (from left to right): L before Z, I before S and J before O.

Second Bag and later
Ideally, one should stack like this if S comes before Z then J, it can be made to a 6-line Perfect Clear after a T-Spin Double.

This way has an extra solution.

If the above is not feasible, one can go for 8 lines in one of these three stacking methods.

The first is the most ideal. It involves needing the S piece berfore the L piece. The Perfect Clear probability is 88.81 %.

If one cannot make a Perfect Clear, they may still be able to make a Perfect Clear after 12 lines. Below is an example.

If either S comes before Z or Z comes before O, then the below is the stacking method. The Perfect Clear probability is unknown.

If one cannot make a Perfect Clear, they can make a T-Spin Double, in most cases, one of these 2 ways, and may also result in a 12-line Perfect Clear.

If O comes before Z, then the third stacking method is as follows. The Perfect Clear probability is 40.71 %.

If one cannot make a Perfect Clear, it can be followed by LST stacking. If they can, they may go for 12-line Perfect Clear.

Late O Piece
An alternative is placing the O tetrimino after the T-Spin Double as in the diagrams below.

It forms exactly the same shape as TKI 3 Flat Top. Some examples of continuations:


 * 6-line Perfect Clear


 * 8-line Perfect Clear
