Start the Square-1 Simulator. The main idea of the solution is the same as the Rubik's Cube method : We divide the puzzle into layers and solve them one by one, not messing up the pieces already fixed.
This puzzle has a completely different mechanism, so we have to introduce new notations and algorithms. Square-1 scramblers usually neglect the slice move. Equivalent to the D move on the Rubik's Cube. The puzzle is much easier to work with when it is in the shape of a cube.
Try to bring the Square-1 to a cube shape in the first step. This is not a complicated stage because there are no solved pieces you can mess up. Use this step to familiarize with its operation.
How to Solve the Rubik’s Cube: An Easy Tutorial
Try to group the small pieces together to form a cube with the method below. The two examples below describe how to make a cube from two easy-to-reach positions, when the thick pieces are collected in the bottom and the narrow pieces are grouped together on the top, as much as possible.
Case 1 : If every small piece is grouped in the top layer.
Case 2 : If there's a lonely small piece in the top layer. To bring the cube to a square shape first you need to collect the tiny pieces next to each other or leave maximum one lonely piece between two thick corners.
This is not that hard to accomplish, it can be done intuitively.
When this is done follow the steps on the pictures above. The black vertical line marks where to make the slice.
How to solve the Square-1
First bring all corner pieces to the corresponding layer: Hold the cube with the red side facing you and the green on the right. The yellow has to come to the top and the white to the bottom.
This step is not so complicated, it can be done intuitively, if not, here's a little help to swith two pieces in the top and bottom layers:. When every corner is in the correct layer, bring the yellow corners to their final position, swithching two pieces in the top right side:.
Yellow edges to the top, white edges to the bottom layer. To swap two pieces move them to the top right and bottom right of the cube then do the algorithm. Repeat this until every edge gets to its layer. It doesn't matter if they're not on the exact final spot. At the end of this step you should see the white and yellow faces solved. In the second step we sent every top-layer corners to their final position.
Now do the bottom corners. Use the trick below to swap the two front-facing corners in the bottom layer. At this point every edge should be at its correct layer, we just have to put them to their final position.
Switch two pieces on the top and two in the bottom layer at the same time. The algorithm below switches the right-top with the back-top edge and the right-bottom with the back-bottom edge.
In most cases your Square One puzzle should be solved at the end of this step. If there are two edges that need to be fixed then you have a parity. Use this long algorithm to switch two edges on the top then go back to point 5.
