This page is a place for Fumens of uncompleted (prototype) setups created by Tetris players, advisably involving make-your-own Twist and Spin techniques (although other techniques are fine), to be shared in the form of a View-type Fumen.

The setups in the second and third Fumen were named Windsor SD and Windsor Mini by Chopin.

The setup in the fourth Fumen was named 閉塞 (Heisoku)/Blockade by CaptainCream.
