Lawrence Leung’s Rubik’s Cube solution

Lawrence Leung 45 second cube solve

Lawrence Leung may not be the fastest as solving the cube – 45 seconds is nowhere near the world record of 5 seconds held by Lars Petrus. But lawrence has certainly has taken cube solving to another level – in his ABC TV series; Lawrence Leung’s Choose Your Own Adventure he attempts to solve the rubiks cube in a number of dangerous locations and situations as he attempts to set a new world record using the Rubik’s Cube.

Rubik’s Cube tutorial – How to solve the first layer

In this tutorial you will learn how to solve the rubik’s cube using the layer method. There are many other methods you can use. But the layer method is the easiest. In the layer method you begin by solving one layer or face of the rubik’s cube – nine – but the centre piece does not move. You begin by making a white cross, the cross pieces have two colours. Once you have made the cross you now need to solve the corners. The corner pieces have three colours. Here we have the white green and red piece and we want that piece to go up here. We do that by using a sequence of moves. You want to end up with the piece below the actual position you want it in then move it up to the correct position. There’s one more piece to go, there it is, lets take it up to here using three moves. Describe algorithm. There it is the first layer solved.

So it’s time to solve the middle layer. To solve the middle layer there are only four pieces that you need to move. Because the centre pieces don’t move they denote the colour of the face. For example if you wanted to move this piece here, the green and red piece into the green and red piece here I use 8 moves. Describe algorithm. Repeat the same 8 moves to move each piece altering the direction. Describe algorithm. Repeat the same 8 moves to move each piece altering the direction. Describe algorithm.

Rubik’s Cube tutorial – How to solve the final layer

The final layer is actually the complex layer to solve. At this stage you should have a yellow cross – as you can see here. I will start by moving the corner pieces into the correct positions. As you can see 1 piece is already in the correct position. But the three remaining pieces are not. So I will shuffle those three pieces around until they end up in the their right positions and to do that I have an algorithm to move those pieces. Describe algorithm. I have shuffled them once but as you can see they still need to move around one more step. There you go now you can see all the pieces are now in the correct positions. All three remaining pieces are now in the correct positions they are just not facing the correct way – which is yellow face up. So in order to shift these pieces around within shifting their positions I do use the following algorithms. Describe final algorithm.
