Maospin

Maospin is a setup which starts with a single line clear T-Spin Fin in the first bag, followed by a T-Spin Double in the second bag, STSD in the third bag, and a 100% Perfect Clear finish in the fifth bag. Unlike most T-Spin Fin setups this setup only clears one line in the first bag due to the setup not wasting the first T piece. This setup was made by and named after Maosense.

First Bag
The build chance of the first bag is 100% as long as I and O come early.

Second Bag
One can always stack the second bag like this.

Third Bag
If J comes early, building the stack below is always possible. One can always stack the third bag like this. This will still lead to a 100% Perfect Clear field with 5 minimal solutions but this build's solutions require a little more trickier memorization.
 * Normal Build
 * Alternative Build

Fourth Bag
One can always stack the fourth bag like this.
 * Normal Build

One can always stack the fourth alternative bag like this.
 * Alternative Build

Perfect Clears
Both of the PC fields yield a 100% success rate. 6 minimal solutions. The first solution covers roughly 85% of all bags which is why the normal build is the optimal build.
 * Normal Build

5 minimal solutions. The first solution covers about 59% of all bags.
 * Alternative Build

Trinity Stacking
With the alternative build it is possible to create a few trinity stacks. Note that the placements of J and S are the same for all of the 4th bags.

Also Included are 5th and 6th bag examples to continue the stacking where two Z tucks will be able to fill in the well on the right side of the board.
