The Glitter Brooch is a T-Spin Double opener 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.
- S → Z, J → O (PC rate: 94.17%, 29 solutions): This is the most ideal way to get a Perfect Clear in the third bag.
- S → Z/Z → O (PC rate: 50.75%, 10 solutions)
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.
- O → Z (PC rate: 40.71%, 5 solutions)
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.
Alternative continuations
These are alternative ways to stack the second bag and their Perfect Clear probability rates, although averagely lower than the above ways.
- S → Z/Z → O (PC rate: 35.32%, 3 solutions)
- O → Z (PC rate: 41.27%, 3 solutions)
Late O Piece
An alternative is placing the O tetromino after the T-Spin Double as shown in the diagrams below.
It forms exactly the same shape as TKI 3 Flat Top. Some examples of continuations:
- 8-line Perfect Clear (41.27%)
