What is perfect clear ?Edit

Perfect clear is a bonus that rewarded if and only if you clear all of terminos out (including bombs). It send 10 extra garbage line to your opponent.

How to make a perfect clear ?Edit

This guild try to create high chance of success perfect clear. The best senario is to make it at the begining of the game , so your opponent hasn't finished building up their stack. If you success this usally become a K.O.

Note that this guide is not garuntee 100% chance of success in making a perfect clear. And It require a lot of understanding and practices to make it work in a game. However, failure is not as bad because you can continue making stack for T-spin or Tetris.

The process contain 2 steps.

1. Create a stack that have high chance of doing perfect clear
2. Look for terminos combination and make it success.

Stack for perfect clearEdit

This is a stack that give a high chance of success to make a perfect clear. Since it build from a combination of every termino and have 12 holes which fit the next combination of 3 termino.

Acctually it consist of two parts that can be split. first, 4x4 termino, or you can spit this part to 4x3 and 4x1 it doesn't matter

Second, combination of TSZ which very important here. Note that you should get T before Z to make this shape.

Which mean it possible to create a shape like this.

or like this

or this

or a mirror one apply to the similar theory(but not the same), note the difference in TSZ combination.

terminos combination and make it successEdit

Now let assume you finished building stack like the one below

The next thing to worry is what is your next 3 termino. Note that you can use queue to hold one unuse termino. As a tetris player, you should know that the sequence is very important in many case.

LTIEdit

Successful position is shown here. This combination work regardless the order of termino. But L before T is easier, otherwise it required L spin technique.

first, insert L into the position by soft drop it

Then spin clockwise once.
