SingleYou

SingleYou, or Single Double Perfect Clear (SDPC) (Japanese name SDパフェ), is an opener that starts with a T-Spin Single resulting in a 3-wide well. It is notable for having few dependencies (O before S, Z, or T) and many reliable continuations.

In all continuations, the first bag is stacked like so:

The routes differ from the second bag onward.

Perfect Clear
The original continuation, invented by Yuu. The term "SDPC" usually refers to this route.

By setting up a T-Spin Double as follows, one can achieve a high chance of an 8-line Perfect Clear.

The two main solutions are shown below. Together, these provide a 75% solve chance, with a 52% chance of a T-Spin Single or Double.

The remaining solutions are shown below. With these, the solve chance increases to 97%, with a 55% chance of a T-Spin Single or Double.

If a perfect clear is not possible or if the player has already been sent garbage, sometimes you can make a T-Spin Triple or an Imperial Cross.

Late J Tuck
If the J piece is late, but the Z isn't placed yet, you can avoid a mid-air tuck with a 180 rotation. This can be useful if you have fast soft drop.

Alternate O Placement
You can also place the O piece on the other side:

This allows for an increased Tetris chance, as well as an increased solve rate overall.

The solve chance for this setup is 98.5%, with 72% resulting in a T-Spin. There are 8 solutions where pieces are not split into 2 halves and they have the best chance of working: One of them will work for 88.5% of all third bags whereas 66% yield a T-Spin as well.

Motchi PC
Motchi PC (Japanese name もっちパフェ) is an additional set of three Perfect Clear setups that aim for almost 100% PC rate.

All solutions can be found here.
 * LZ → I (100% PC rate, 14 minimal solutions): The best setup to go for if possible, with the first three solves covering almost 75% of all bags (and 86.6% for first five).


 * All bags (99.96% PC rate, 15 minimal solutions): For cases where the above doesn't work out, you can always go for this. (First three cover 65.4% of bags, and first five cover 74.6% of bags)

 * J → O (99.80% PC rate, 18 minimal solutions): This may be the lowest of the three, but it's still a very good extra setup to learn. (First three cover 69.3% of bags, and first five cover 78.4%)

Mechanical TSD v2
The second bag is stacked as in the.

From here, Mechanical TSD v2 can be stacked on top.

Once sufficient height is achieved, the bottom T-Spin Single can be upgraded to a T-Spin Double.

Perfect Clear after 14 Lines
It is possible to achieve Perfect Clear (74.76%, 11 minimal solutions) with the base of Mechanical TSD. Found by Winterfrost and HDChung.

11 solutions are listed below. The most common solution resembles the last Perfect Clear in BT Cannon.

SDPC Spin
Invented by Ecchou. This sends the same attack as Stickspin, but is simpler to build.

Third bag
There are two ways to stack the third bag. The first is always possible, but the second results in a flatter stack.

If the first build is used, the center area must be filled in to complete the T-Spin Double. This can be done freestyle or using the STMB Cave continuation below.

Stmb cave into Stsd
Created by Stickmancomic. This requires the first build to be taken for the third bag. J needs to come before L or Z in the first setup.

Taking the second cspin build
If the Z comes too early, you can put the Z on top of the J piece.

First build
Leads into 6-3 very nicely. Covers 91.67% of all fifth bags.

Second builds
Made by swng

Extension
Builds a 6-3 stack, as well as pressuring the opponent with T-Spin Singles. This is especially powerful in games like TETR.IO which reward Back-to-Back.

Second bag
This can always be built, though you might need to wait for gravity if the O piece arrives late.

Third bag
There are 2 congruent builds that add up to make it 100% coverage

Fourth bag
Here, you take a tsd and a tetris as well.

Fifth bag
While there are some builds here, it would be better to simply go into midgame

SingleYou extension
You can then build SingleYou again on top of the residue.

This is almost always buildable, though you might need to skim if the O arrives late.

Extended sdpcspin build
Developed by cringemoment, this allows you to stack T-Spin doubles far after the c-spin, and transitions into a 6-3 stack.

Fourth bag
The exact same as the normal sdpcspin build, just on top of the well.

Fifth bag
Here you need J before O. You can either take a different build, or skip the b2b.

Sixth bag
This is not a 100% build either, but has fairly high coverage.

Note that this build is also possible sometimes, with a 68.10% perfect clear chance, leading into second perfect clear.

Seventh bag
This build covers 91.67% of all bags. You can take the t-spin in either hole.

Eighth bag
100% coverage, however, you will need some awkward spins to get it to full coverage.

Again, you can take the t-spin in either hole.

Ninth bag
This is a 100% cover build if you switch the JLO box around

Tenth bag
Here, you can take either put the S piece below the O piece, or put it in the well for the fractal.

Perfect Clear after 14 Lines
This loop was found by Winterfrost and HDChung.

Up to second bag is same as the normal SingleYou. However, unlike the normal SingleYou, it results in 2 T-Spin Singles, a Tetris usually, and 100% Perfect Clear instead of Perfect Clear in the third bag directly, without need of using DPC for a loop. Therefore, this continuation is especially useful in games where B2B chaining is rewarded such as TETR.IO.

Third bag
This is possible when J comes before T and L both are placed.

Fourth bag
This is always possible to build in games with 180° spins. Otherwise, J needs to come before S.

Fifth bag
100% PC chance with 5 minimal solutions, all of which are shown below.

3rd bag
This is always possible, but will lead to less attack potentially.

4th bag
There are two versions of 4th bag. The first pattern has more stable attack than the second, but the second one will possibly have a combo tetris attack.

5th bag
Both options have 100% Perfect Clear chance. Both options have 6 minimal solutions, all of which are shown below.

First Pattern
