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.

• S → L (PC rate: 88.81%, 30 solutions): This is the most ideal way to get a Perfect Clear in the third bag.

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

• S → Z/Z → O (PC rate: 50.75%, 11 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:

• 6-line Perfect Clear

• 8-line Perfect Clear (41.27%)

• Mechanical TSD
