How to Solve the 2x3x3 Rubik’s Cube (Domino Cube)

Understanding the Domino Cube

Before jumping into the steps, it helps to understand the cube’s mechanics:

2 layers high

3 layers wide and 3 layers deep

The middle layer rotates like a standard cube.

The top and bottom layers only turn in 180° increments (no 90° turns!).

This restriction is key—it influences which moves and algorithms are possible, and shapes your solving strategy.

Step-by-Step Solving Strategy

Step 1: Solve One Full Face

Start by solving one complete face—typically white or yellow—along with the adjacent edge pieces that sideh the colorsmatc.

This step is intuitive:

Build a cross.

Insert corners.

Ensure that side stickers of the edges match adjacent centers.

At this point, one face will be fully solved, and the middle layer edge pieces will likely be scrambled.

Step 2: Solve the Middle Layer

Now focus on placing the 4 edge pieces in the middle layer correctly.

Use only 180° turns on the top and bottom to maneuver pieces around without disturbing your solved face. There isn’t a single “universal” algorithm here—you can often solve this layer with logic and a few short intuitive sequences.

Step 3: Solve the Final Layer

This step has three parts: positioning corners, orienting them, then solving the remaining edges.

a. Position the Corners

Make sure all four corners of the last face are in the correct locations, even if they’re not oriented correctly.

Algorithm to swap corners:

R2 U2 R2 U2 R2 

Repeat as needed to cycle the corner pieces into place.

b. Orient the Corners

Now rotate the corner pieces so all face colors match their adjacent centers.

Corner orientation algorithm:

R2 U2 R' U2 R2 

Use this on a corner, then rotate the cube to the next one and repeat.

c. Solve the Edges

At this point, your last 4 edges may need to be cycled into place.

Edge cycle algorithm:

U2 R2 U2 R2 U2 

This will swap top-layer edges. Repeat until solved.

Final Thoughts and Tips

The 2x3x3 is restricted by its 180° top and bottom turns, which makes solving feel very different—but also simpler in many ways.

No need to worry about parity or complex edge orientation algorithms.

Most moves are just combinations of R2, L2, U2, D2 and strategic positioning.

This cube is a great step into the world of non-standard puzzles—challenging enough to be fun, but simple enough to solve without needing dozens of algorithms.
