Hyper Fractal

The Hyper Fractal is an easy recursive setup for multiple T-Spin Doubles. Recursive in this case means, that after each T-Spin Double the board is in a similar state to setup the next T-Spin Double.

Introduction

for every piece there is a prefered spot where you want to place it. The S,Z and O-pieces should be placed on their stacks. the J-pieces are placed in the well atop each other. the L-piece is used to create the T-shaped holes. The I-pieces should be placed in pairs on the O,S or Z-Spots. And finally the T-piece is used for the T-Spin. When everything comes together it could look like this:

Helpful advice

Another useful technique for balancing the stack is J-skimming (L-skimming in the mirrored setup) if the J-stack is to high. By rotating a J-piece instead of an L-piece, it creates a shape that can be cleared with either an S or a Z-piece. That operation just clears an J-piece from the stack so the board will be in the standard state again. It is also possible to place the S or Z-piece first and skim with J or L-piece later.

J,S,Z-Skimming:

Use J-piece

to create S,Z-cave

S,Z-cave

Skim with S-piece

Or skim with Z-piece
