- 1. Rubik’s cube solution By Ibrahem Batta
- 2. Rubik’s cube
- 3. Pieces• There are three different kinds of pieces. Centers
- 4. PiecesEdges
- 5. PiecesCorner
- 6. Mistake• The stickers is the visible face of cube .• Many people make the mistake to think that rubik’s cube has 54 stickers need to be solved .• In fact it only has 20 pieces to be solved.• 8 corners and 12 edges .
- 7. NotationYou will need to learn move notation in order touse this solution. Right RThe six cube faces will be represented by Left L Up U Down D RLUDFB Front F Turns that face clockwise Back B R’ L’ U’ D’ F’ B’ Turns that face counterclockwise R2 L2 U2 D2 F2 B2 Turn that face 180 degrees
- 8. MethodThis guide teaches the layer-by-layer (LBL) method.The first layer is the most intuitive and the lastlayer requires the most memorization.
- 9. The first layerSolving the first layer is a two-step process:• solve the edges to make a cross and• solve the corners.Remember that edges and corners have multiplestickers and belong in a specific position!
- 10. First layer cont.Solving the cross• Define a goal and assume it the piece in the center the top surface in our example it is white .• find the edge you want to solve , and this may be any edge.• You can determine the correct position to piece by checking the two other faces of piece.
- 11. First layer cont. Let piece up layer by layer if it in last layer
- 12. First layer cont.Solving the corners• Figure out where the corner belongs by checking the two non-white stickers on the corner.• bring the corner above the goal .• Apply one of the following algorithms.
- 13. First layer cont.Algorithm Algorithm Algorithm(U R U’ R’) (U’ F’ U F) 1. (R U’ R’ U2) to get the white sticker on the side 2. Use one of the algorithms above to solve.
- 14. First layer cont.Algorithm Algorithm Algorithm(U R U’ R’) (U’ F’ U F) 1. (R U’ R’ U2) to get the white sticker on the side 2. Use one of the algorithms above to solve.
- 15. First layer cont.By finishing the first layer the result well be like this
- 16. Second layerThe Second LayerThe second layer only has four edges that need to besolved. The centers never move, so they are alreadysolved!
- 17. Second layer- If the edge in last layer => * check the 2 faces to determine its correct place. * Bring the edge next to the goal so that the front stickers match by using either a U, U’, or U2 move. * Apply one of the following algorithms. Algorithm Algorithm U (R U’ R’) (U’ F’ U F) U’ (L’ U L) (U F U’ F’)
- 18. Second layer- If the edge in second layer=> Algorithm 1. (R U’ R’) (U’ F’ U F) to get the edge to the last layer. 2. Use the method above to solve.
- 19. Second layer- If the edge in second layer=> Algorithm 1. (R U’ R’) (U’ F’ U F) to get the edge to the last layer. 2. Use the method above to solve.
- 20. Second layerThe result of second layer solution
- 21. Last layerOrienting the edgesThe goal for this step is to make a yellow cross.Algorithm (F R U) (R’ U’ F’)
- 22. Last layerOrienting the cornersThe goal for this step is to make all the corners yellow. The following diagrams are drawn as top-down views, so you must hold the yellow face ontopAlgorithm (R U) (R’ U) (R U2) R’
- 23. Last layerPositioning the cornersThe goal for this step is to move the corners into the right placesAlgorithm(R U2 R’ U’ R U2) (L’ U R’ U’ L)
- 24. Last layerPositioning the edgesThis is the final step in solving the cubeAlgorithm F2 U’ (L R’) F2 (L’ R) U’ F2
- 25. Ai and rubick’s cube• Kociembas Algorithm.• Thistlethwaites Algorithm.
