This setup uses an "S" or "Z" piece propped up in abnormal situations to produce T-Spins. Many of these are set up alongside a wall to create the "T" shape needed for a T-Spin Double. It is made popular by player, Blink, who frequently uses it during multi-player. They are similar to Kaidan Setups, but by nature is essentially different to see and perform. Blink S/Z prop is generally used on a flat surface rather than over a Tetris hole, and is usually done Prophecy Style.
The difference between Blink SZ Prop and Kaidan is that the dark gray cell is required in Kaidan.
