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.
Fourth Bag
One can always stack the fourth bag like this.
One can always stack the fourth alternative bag like this.
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.
5 minimal solutions. The first solution covers about 59% of all bags.
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.
The 5th bag piece placements are all examples on how to stack to set up further trinities. Included in the 2nd option is a 6th bag continuation where two Z pieces can be tucked into the right well to continue the stacking.
