# How to solve the 3x3x2 Domino Cube

The Domino Cube is the normal Rubik's Cube without the middle layer. Whilst the Up and Down faces can turn 90° the rest of the faces however can only turn 180° at a time (if you're not sure why, try turning the Left face of your cube 90° and see if you can move any other faces!). This means that when solving the cube there is less orientation to be done as the Up and Down faces will always be yellow or white (or whatever your colours may be). There is also a Circle Domino Cube, this is the same as the normal Domino cube except hte corners have been rounded. This makes it slightly easier to solve as there are multiple solutions because no colour has to go on a particular side. Read on to find out how to solve the Domino cube.

## Notation

Similar to the Rubik's cube, uppercase letters represent turns of the faces. U and D mean a quarter clockwise turn of the up and down face. R, L, B and F mean a half clockwise turn of the right, left, back and front faces. Small cubes that are grey in the following pictures means that their colour does not matter.

F = Front

B = Back

U = Up

D = Down

R = Right

L = Left

## Step 1

The first step to solve the Domino cube is to place all the yellow corners on the correct face and doing this will place all the white corners on the correct face. This is done by eye. After that it is time to position them correctly.

Aim

To do this place two incorrectly placed corners in the back (in the positions marked with x's) in order to swap them with the following algorithm:

Algorithm: R F U F U' R U F U' R

## Step 2

The next step is to get all the edges on the correct face, not necessarily in their correct positions though.

Aim

Find an edge piece on each face that needs to be moved and place them underneath each other, as marked by x's below, on the right side then use the following algorithm to swap them:

Algorithm: D2 R D2 F D2 F D2 F R

## Step 3

The final step is to swap the edge pieces around so that they are in the correct positions.

Aim

There are two algorithms to complete this step. One swaps the bottom right and bottom front edge pieces, the other swaps the up back and up front two edge pieces. The x's mark which pieces will be swapped:

Algorithm: F U R F U2 F U2 F U2 R U' F

Algorithm: R 2U R 2U R 2U
