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

• Normal Build

If J comes early, building the stack below is always possible.

• Alternative Build

One can always stack the third bag like this. This will still lead to a 100% Perfect Clear field but with 5 minimal solutions. This build's solutions require a little more trickier memorization.

Fourth Bag

• Normal Build

One can always stack the fourth bag like this.

• Alternative Build

One can always stack the fourth alternative bag like this.

Perfect Clears

Both of the PC fields yield a 100% success rate.

• Normal Build

6 minimal solutions. The first solution covers roughly 85% of all bags which is why the normal build is the optimal build.

• Alternative Build

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