How to solve the Latch Cube
Cube on the right is the real Latch Cube . Cube on the left is a fake Latch Cube . This fake Latch Cube put stickers on the common Rubik's cube and made it. Which I used when I think about solution. This fake Latch cube was quite serious serious without moving well well because this cube was bargain goods of poor quality. (only one dollar !) The method I use for solving the Latch Cube is layer ba sed method In the same way as solving a Rubik's Cube. And this solving method requires memorising only few algorithms. Then let's begin explanation of the solution. A request: My English ability is very low, there may be many mistakes, but please permit it.
The Solution A final goal of this solution is to make the Cube a state of the left-hand of the lower picture.

After you have completed a Cube like this... L' R
When describing the solution for the Rubik's cube, standard cube notation wil l be used. Here's what you need to know to read it: F = front face B = back face R = right face L = left face U = up face D = down face
In addition to a letter, each move may be accompanied by an apostrophe or the number two or the number three:
・A letter by itself means turn that face 90 degrees clockwise (eg. F). apos trophe means turn that face 90 degrees anti-clockwise (eg. F'). ・A letter followed by an apostrophe ・A letter followed by the number 2 means turn that face 180 degrees , (eg. F2). ・A letter followed by the number 3 means turn that face 270 degrees , (eg. F3). And this solution, sometimes appoints a layer face using the color of the center cube. (eg. if the color of the center center cube is yellow then it's the Yellow face) face)
Step 1. Form the Black arrows cross put at D face
a tip : It is easy to do it after collecting black arrows put at D face first of all.
Here is a finished picture of what a correctly formed Black arrows cross at D face. You need to solve it without learning algorithms. So, please spend some time playing with the Latch Cube and familiarising yourself with how to move the pi eces around the cube.
Step 2. Inserting the 2 middle layer green edge-cubes with the black arrow
open drawing Here is a finished picture picture of two middle layer green edge-cubes are correct position.
Then let's insert green-edge cubes with a black arrow into the correct middle layer layer position. The following picture is one example of the procedure.
The procedure inserting this cube into the correct position...
This procedure mentioned above is one example. White arrows really considerably interferes interferes when you do it. Please be careful careful not to break a Black arrows cross at D face and make trial and error in various ways.
This is an another another procedure for your information. information.
The procedure inserting this cube into the correct position...
In this case even if there is a white arrow in the U face, it is not troubled very much, but if there is a white arrow arrow at the Green face ,it is hard to turn the last F'3. Let's keep keep off a white arrow arrow of the Green Green face. face.
The next , insert another green edge-cube into the correct position.
The procedure inserting this cube into the correct position...

tips: There is generally white arrows in the same U face like a picture if I will move an edge-cube with the black arrow. So please turn it after deleting a white arrow well.
Cumbersome arrows
I think that it is very hard to finish step 1 and step 2. I say once again. These procedures mentioned above are one example. White arrows really considerably considerably interferes interferes when you perform it. Please be careful not to break a Black arrows cross at the D face and make trial and error in various ways. I think that I am not so serious afterward if you collect black arrows on a D face/ a Green face.
Step 3. Inserting the 2 first layer green corner-cubes
open drawing These two corner-cubes.
By the way, there are cases unlike a left-hand picture in the direction of the corner-cube . In that case, please refer to corner the next step "Step 4. Inserting the 2 first layer blue corner -cubes". The procedure inserting this cube into the correct position... The right-side end of the Yellow face.
Turn the last layer ( U3) to move a cube which you want to move. And turn the first layer ( D'3) to move a spot where an objective cube is in.
Turn a Cube so that Yellow face becomes in front.

like this pattern...
Turn a Cube so that Yellow face becomes in front.
Please re-insert it again after getting it out to the last layer of the Yellow face side in this way.

Step 4. Inserting the 2 first layer blue corner-cubes
These two corner-cubes.
I think that this step is not so difficult. It is the same as making the first layer of a common Ru Rubik's bik's Cube. Please be careful to an aspect to do in the front and the directions to turn.
At first from this this side.
When Yellow of the corner-cube is in the right side .
When Yellow of the corner cube is in the front side.

When Yellow of the corner cube is in the up side.
The Cube became the state same as the state that Yellow Yellow of the corner cube in the right side in this procedure.
The next , insert another blue corner-cube into the correct position.
This This side. side.
I perform it after I turn the Cube to Blue face in the front. I think that this one i s easy to perform it.
There are three patterns like above pictures. Please make it with the point same as a former method.
Here is a finished picture of two first layer blue corner-cubes are correct position.
Step 5. Inserting the 2 middle layer blue edge-cubes I think that this step is not so difficult too. It is the same as making the middle layer of a common Rubik's Cube. Please be careful to an aspect to do in the front and the directions to turn. These two edge-cubes. By the way, about Step 4 and 5, the person who can insert the first layer cube, the middle layer cube into the correct position at the same time please insert two cubes at the same time. I do not know a pattern to move these two cubes at the same time. Therefore I move always one by one when I solve a common Rubik's Cube. At first from this this side.
The procedure inserting this cube into the correct position...
By performing this procedure, this cube is inserted ... into the place of the right side .
When the color of the cube is upside-down unlike the picture mentioned above...
U3
Turn a Cube so that Blue face becomes in front.
I do it after I turn the Cube like a this picture. pi cture. I think that this one is easy to make it.
On the other hand, by doing this procedure, this cube is inserted ... into the place of the left side.
The next , insert another blue edge-cube into the correct position.
There are two patterns like left-hand pictures. Please make it with the point same as a former method. Please be careful to an aspect to do in the front and the directions to turn.
When the direction of the aspect of the edge-cube that you want to move has already entered by mistake.Please re-insert it again after getting i t out once to the last layer in this way. (U) R U3 R3 U3 F3 U F
A cube comes out to the third layer in this procedure. Sorry I do not know a procedure to reverse on the spot.
You were able to complete the Cube to the middle layer by a step to here.
Step 6. Form the White arrows cross put at U face Here is a finished picture of what a correctly formed White arrows cross at U face. There are two finished patterns like following pictures.
The pattern of the U face when it was completed to the middle layer l ayer has it of 4 like following pictures.
The important thing is position of the white arrows, and please do not mind the color of the cube (red or black). When I form the White arrows cross of the U face, I perform this procedure after having rotated the Cube the Green face in the right side . It is not necessary to rotate Green face to the right side, but is in this way because because it was necessary to rotate rotate Green face to the right side to do it in the same way as the procedure that I usually use.
Therefore please have the Cube like a left-hand picture. front: Red face, right side: Green face
The White arrows cross is formed sequentially as follows when you perform this algorithm "L U F U3 F3 L3" repeatedly.
L U F
3
3
L U F

L U F

You need to do this procedure correspondingly with the state of U face.
Step 7. Fix the color of the U face It is the same as the color of U face is white or the color of the U face is blue state in case of a common Rubik's Cube. In this case ,you need to keep the White arrows cross at the U face and to fix the U face color of four corner-cubes are all red . There are two finished patterns like left-hand pictures.
The algorithm that I know is only one. "R U2 R3 U3 R U3 R3" In this procedure , you need to perform it "hold the Cube so that the Yellow face is on the front", and "change the last layer position". The following following pictures are the pic of looking at the U face from the top with a Yellow face as the front. "The state that the U face is completed i n another one time procedure" is the state of the left-hand picture. This red stick shows the direction that there is the red color that shou ld be suitable for the U face.
It is completed like the right picture by performing this algorithm "R U2 R3 U3 R U3 R3" in a state of "The state that the U face is completed in another one time procedure". R U2 R3 U3 R U3 R3
There are the following patterns when you pay attention to only the white arrows cross and red of the corner-cubes. go to the next page
All the algorithm that an arrow shows are "R U2 R3 U3 R U3 R3" .
I say again, in this procedure , you need to perform it "hold the Cube so that the Yellow face is on the front", and "change the last layer position". Please perform this procedure after correspond with the s tate of U face of your Cube to the above picture. By the way, in the procedure mentioned above, corner-cubes of the last layer (U face) are moved as follows.
①
②
④
③
③
④
②
①
Though it may be hard to be understood only in a picture, ① is switched with ④, and ② is switched with ③. When these cubes are switched, ② moves at the position of ③ in the same state. As for the ① ③ and ④, these cubes move to the opposite position on the diagonal with counterclockwise turn. For example, the cube ④ of the above picture moves to the position of ① with turning like a right picture. You can predict a state state of the next U face pattern pattern after performing it at a color and a position of the last layer of each corner-cube, even even if you do not remember remember a pattern to fix the U face if you understand even the movement of this cube. The person with the interest , please identify a position and the color of the cube while performing this procedure.
Step 8. Orienting the last layer corner-cubes into the correct position When you finished the Step7, I suppose your Cube to be the state such as the following picture. "keep white arrows cross at the U face" and "the U face color of four corner -cubes are all red "
This picture is an an open drawing drawing only of the last layer.
It is necessary for these two corner-cubes to be switched each other.
This situation , actually...
It is necessary for these two corner-cubes to be switched each other.
It becomes like a left-hand figure when I turn the last layer layer "U3". This picture means that, that, Two of Four cornercornercubes were inserted into the correct position. In this case, I should switch a position on a diagonal with remaining two and I cannot switch two cubes located on a diagonal. The Cube of this situation has to be switched here and here.
U3
I can not switch these corner-cubes!
Therefore I have to switch two corner-cubes each other, two times . The algoritm is "R U2 R3 U3 R U2 L' U R3 U3 L'3".
R U2 R3 U3 R U2 L' U R3 U3 L'3
Looking at the U face from the top, it is such a thing.
At this time, the position of the edge cube of the White cross changes, too, but does not need to mind it.
The next is cube replacement of two remainder. At first , turn the last layer " U2". Two cubes which you want to switch next are moved by this this operation to the Blue face.
U2
R U2 R3 U3 R U2 L' U R3 U3 L'3
Please perform the same algorithm in this s tate. (switch two corner-cubes each other.)
This is the the same operation operation as above.
Please turn the last layer to the correct position after you replaced all cubes in the correct position.
U2
By this step, both the position and the color of the corner-cubes of the last layer were adjusted. The completion picture mentioned above is one example. At this stage, the thing necessary are, to keep the white arrows cross at the U face and both the position and the color of the corner-cubes of the last layer were adjusted. Therefore, in above picture, the color of the U face of edge-cubes with a white arrow constituting a White cross is OK with both the red and the black.
Step 9. Permuting the last layer edge-cubes into the correct position As I wrote it first, a final goal of this sol ution is to make Cube a state of the following picture.
open drawing
Therefore , for example, edge-cubes of the last layer in the case of the placement such as the following picture...1 edge-cube is correct and 3 edge-cubes are incorrect. Looking at the U face from the top.
= incorrect edge-cube Fix the edge-cube at a correct position to the Green face...
R3 U2 R U R3 U R U R U2 R3 U3 R U3 R3 U3
3 edge-cubes move like the right-hand picture by performing this algorithm. Seeing from the top, it is the movement of the counterclockwise turn. Sorry I do not remember the algorithm of the clock turn. In addition, the following cases are ... Looking at the U face from the top.
= incorrect edge-cube Looking at the U face from the top.
At first , fix the edge-cube at a correct position to the green face (turn the third layer " U"), thereafter, thereafter, please perform this algorithm "R3 U2 R U R3 U R U R U2 R3 U3 R U3 R3 U3". If all 4 edge-cubes are incorrect, then perform this algorithm above once, and then determine the three edge-cubes need to move and perform this algorithm again.
Step 10. Celebrate your cubing success! Congratulations, your Latch Cube is solved! Then let's perform the last algorithm "L' R".
