11. How To Solve A Rubik's Cube

How To & Solve A Rubik's Cube THINGS TO KNOW BEFORE YOU START The square in the middle of one side indicates that sides' colour. eg. green square = green side. Always hold the cube so the 'Front' face is towards you when completing moves. The 'i' indicates the move is inverted or counter-clockwise in direction. Each turn is 1/4 turn rotation/90°. LAYERS Top Middle Bottom MOVES FRONT (F) LEFT (L) RIGHT (R) UP (U) DOWN (D) FRONT INVERSE (Fi) LEFT INVERSE (Li) RIGHT INVERSE (Ri) UP INVERSE (Ui) DOWN INVERSE (DI) STEP 1: CROSS STEP 2: CORNERS STEP 3: MIDDLE STEP 4: TOP CROSS STEP 5: TOP CORNERS A. Locate the centre orange square and place that side as the top layer. B. Locate centre orange pieces and rotate so they are in the bottom layer, lining up with it's corresponding colour. Turn F 180°. c. Repeat for other 3 centre pieces until cross is achieved. A. Locate orange corner piece in bottom layer and rotate to it's corresponding corner colours. B. Do sequence: Ri Di R D. Repeat until orange is in the top layer, correctly placed. c. Repeat for other 3 corners. A. Flip the cube orange layer now on bottom. Find and rotate centre cubes int top layer to match colours with middle layer. B. Use left or right sequence depending on which direction the colour in the top layer needs to go. Left: Ui Li ULUF Ui Fi Right: UR Ui Ri Ui Fi U F Repeat until middle layer is completed. *COMPLICATION* A. Locate L-shape in top layer. Rotate so it's in the top-left corner. Do: FRU Ri Ui Fi.. Repeat for horizontal line, and again for cross. B. Rotate top layer until 2 adjacent centre cubes line up with centre cubes of middle layer. C. Place one side at the back and the other on the righthand-side. Do sequence: RURI URUU Ri Ui. All centre cubes will line up with the middle layer. A. Rotate top layer so one corner is corresponding with it's corner colours and place in bottom-right. B. Do sequence: URUI LIU Ri Ui L. Repeat sequence if required, keeping the correct corner in the bottom-right, till all corners have corresponding correct colours. Some or all the colours will be scrambled. C. Starting with the bottom right colour, do: Ri Di R D. Repeat until corner is completed. Rotate ONLY the top layer Ui, and repeat sequence for other corners. *COMPLICATION* If the piece is switched around, do: F U Li Ui. Colour is switched after completing all sides. Do left or right sequence and this will bring it to the top layer. Repeat step b. *COMPLICATIONS* Only i. singular cube or, ii. horizontal line, in step A. i. Do step (a) sequence for L-shape. ii. Do A sequence for cross, Opposite sides match up in step B do sequence in Cand continue from B D. Rotate top and bottom layers to match middle layer colours. COMPLETE!
