The Steps of Tetris


Tetris is played layer by layer, and the algorithms are based on those of 3x3x3.

Step 1

The 1st Layer

When the layer is fully completed, your cube will look like this:

No specific algorithm.

The placement of the pieces should remain intuitive.

Here are the main steps:


The Centers


The Edges


The Corners

Step 2

Placement of the Edges of the 2nd Layer

Once all the edges have been processed, your cube will look like this:

Case of the blue edge

Place the blue edge
on the 3rd layer opposite


The algorithm allows you to place it on the 2nd layer.

Case of the green edge

Place the green edge
on the 3rd layer opposite


The algorithm allows you to place it on the 2nd layer.

Case of the yellow edge

Place the yellow edge
on the 3rd layer opposite


The algorithm allows you to place it on the 2nd layer.

Case of the red edge

Place the red edge
on the 3rd layer opposite


The algorithm allows you to place it on the 2nd layer.

Step 3

Placing the edges of the 3rd layer

When all the edges have been processed, your cube will look like this:

Case a

The blue edge serves as a reference
The other 3 edges are incorrectly placed
The yellow edge is at the back and must be placed on the right


The algorithm will perform a circular permutation in a clockwise direction.

Case b

The blue edge serves as a reference
The other 3 edges are in the wrong position.
l'arête orange est à l'arrière et doit être placée à gauche


L'algorithme va effectuer une permutation circulaire dans le sens antihoraire.

Cas c

L'arête bleue sert de référence
2 autres arêtes sont mal placées
l'arête orange est bien placée à gauche


Cette formule va placer les arêtes Left / Back.

Vous pourrez alors appliquer l'algorithme du cas a.


Cas d

L'arête bleue sert de référence
2 autres arêtes sont mal placées
l'arête jaune est bien placée à droite


Cette formule va placer les arêtes Right / Back.

Vous pourrez alors appliquer l'algorithme du cas a.


Case e

The blue edge serves as a reference
Two other edges are incorrectly positioned
The green edge is correctly positioned at the back


This formula will position the Right/Left edges.

You can then apply the algorithm for case a.

Step 4

Positioning the corners of the 3rd layer

When all the corners have been processed, your cube will look like this:

Positioning the yellow and orange corners

The algorithm will swap the corners of the top face (except the one in front of you at the top right) clockwise.

Depending on your setup, you should apply the algorithm a maximum of 2 times for yellow and 2 times for orange!

Place the red and blue corners

The algorithm will swap the Front corners (except the one in front of you in the bottom right) clockwise.

Depending on your setup, you should apply the algorithm a maximum of 1 time!


Your Tetris puzzle is solved.
