WolfMoon Cannon

WolfMoon Cannon/WM Cannon is a setup which starts with a T-Spin Fin which was then continued by an Impeldown and ends with an 100% chance of a 14th row Perfect Clear. This setup is systematically unique and looks quite eccentric to some, but if Perfect Clear is achieved, it could send at least 29 garbage lines to a player's opponent. This setup is made by and named after a Korean Twitch streamer WolfMoon/랑월 with the aid of another Korean Twitch streamer cooj/쿠우즈/jaehyun0411.

First Bag
The build chance of the first bag is 100% as long as either L or J is early and the mirrored setup is considered.

Second Bag

 * Normal Build

If J comes early in the second bag, building the stack below is always possible. If J is not early however, T has to come before either Z or L.

If J and Z are placed early, T requires 5 spins and L requires 3 spins at least.


 * T piece


 * L piece


 * Alternative Build

Since the second bag does not has a consistent build chance, player could make a Cut Copy looking stack instead. This could always be made if the usual continuation is impossible, since it only needs an early Z. The J and O configuration does not really matter. This continuation was invented by player jyin.

Alternative, much more cleaner variation of the stack above.

Third Bag
There are three ways of stacking the third bag.

Alternatively, players can stack them like these if the builds shown above were not possible, although, these stacks do not connect to another continuation.

Fourth Bag
There are two ways of stacking the fourth bag. If it is not possible to make, player could just stack freely until the Fractal has been fully used.

Fifth Bag
In the fifth bag, there is a 100% 14th row Perfect Clear chance, with some patterns containing a T-Spin Double and/or a Tetris.
