Mochi's Anger (Japanese name もっちの怒り) is a T-Spin setup arranged like Pelican, but the I piece is placed on the right side instead of the left. It is a flexible opener and offers players multiple options to stack their second to fifth bags.

First Bag

Second Bag

You will need Z to come before S.

The second bag can also be arranged like this (use when you have an early JS):

Third Bag

You can either make a T-Spin Double or T-Spin Triple.

When the second is stacked the first way, you can make a T-Spin Double or Triple in one of two ways.

• T-Spin Double: Only S before O is required.

• T-Spin Triple: Try this if you get an early O.

If the second bag is stacked the second way, you can make a T-Spin Triple. You will need S and O before L. It will lead to the same stack as above.

Fourth and Fifth Bags

If you stack a T-Spin Double from the first way, stack another T-Spin Double. O and I need to come last.

In the fifth bag, it may be continued with a Perfect Clear after 12 lines. Tetris may be done on the first solution.

If you cannot stack the above, here are some other ways to stack. Some of these stacks may result in a chance of Perfect Clear after 14 lines.

If either T-Spin Triple continuation is used, then one can make another T-Spin Double. It needs O before S and Z before I only. It may be followed with a Perfect Clear.

Below is another way, but it needs L before I instead. Two solutions are shown, but there are more.

Perfect Clear after 8 lines

You can achieve a Perfect Clear after 8 lines if you can stack a TST T-Spin Double like below; only O before I and S is kept on hold.

Here are some solutions, with some with the held S piece. You have 7 pieces to place instead of 6.
