★1～★5まであります。★1でも回転入れを知らなければ難しいと思います。★xは癖が強い問題です。
問題番号は作成した順番です。新しい問題は割りとマシなのが多く、古い問題はあまり良くない傾向にあります。

例えば、" TSD2 " は " T-spin Double を2回せよ " という意味です。LSDならL-spin Doubleを意味しています。PCはPerfectClearを意味しています。" TSD1,TST1 " は、TSDからTSTをせよという意味ではなく、順序は問いません。Holdは用いても構いません。

問題はなるべく別解がないように作ってありますが、別解（例えば、テトリミノがあまった状況で問題が解けてしまう、
明らかに簡単な解法で解けてしまう、など）を見つけた方は、下のところにコメント（問題番号と解答を貼り付ける等）をしていただけると非常にありがたいです。日本語でも大丈夫です。

There are levels ★1 to ★5. Even at ★1, it may be challenging if you are not familiar with SRS rotation. ★x contains many peculiar question. The problem numbers are assigned in the order of creation. In general, newer problems tend to be relatively better, while older problems exhibit a less favorable trend.

For example, "TSD2" means "Perform T-spin Double twice," and "LSD" signifies "L-spin Double." "PC" stands for Perfect Clear.
Expressions like "TSD1, TST1" do not imply a specific order; it doesn't matter if you execute TST before TSD. The use of the hold is also acceptable.

The problems are designed to have as few alternative solutions as possible, but if you discover alternative solutions (for example, solving the problem with leftover tetriminos or finding an evidently simpler solution), I would greatly appreciate it if you could paste the problem number and solution in the cell below.

No.21 should be TSD1, while a TST would be mathematically impossible given only 8 pieces. fixed

No.1 I found this and thought this is intended. the well is a bit sus,though1fixed
12
No.144 An imperial cross solution144fixed

No.33 I don't think a 7p PCO solve is worth 3 star, found it in 20 sec. It would be cooler if the intended solution is the 6p PCO solve. (There are a lot of alt sol. though)33fixed
14
No.122 There are, in fact, 10 solutions. I found the 10th one in 20 sec.122fixed
