The exercises intend to focus on basic formula without involving the faces of B, D, E and S. It is difficult for intermediate player to rotate the sides of B, D, E and S. 16624306985Position : Front Determine your Front (F) face and do the following permuation. 2.1 Exercise 1 58185058191551060358191543935658191536810958191529686258191522561558191515436858191583121581915 a) 510603514795543935651479553681095147955296862514795522561551479551543685147955831215147955 b) 43935659906036810959906029686259906022561559906015436859906083121599060 c) 510603516446543935651644653681095164465296862516446515436851644658312151644652256155164465 d) 2968625127022561551155701543685115570831215115570 58185051143051060351143043935651143036810951143029686251143022561551143015436851143083121511430 f) 2.2 Exercise 2 (B, D, E and S faces are excluded ) 48685456223042748206223036810956223030873706223024936456223018999206223013061956223071247062230 a) 30873707239036810957239024936457239018999207239013061957239071247072390 b) 48685457556542748207556536810957556530873707556524936457556518999207556513061957556571247075565 c) 60559958191554622708191548685458191542748208191536810958191530873708191524936458191518999208191513061958191571247081915 d) 2.3 Exercise 3 (B, D, E and S faces are excluded ) (a)F U R Ui Ri Fi (b)F R U Ri Ui Fi (c)R U Ri U R UU Ri (d)Li U R Ui L UU Ri U R UU Ri (e)FF U L Ri FF Li R U FF (f)U R Ui Ri Ui Fi U F (g) U R Ui Ri [ E D ] Li U L In fact, formula of (f) and (g) generate the same outcome for second layer. When you use the formula of (f) above you will experience using (g) automatically. Soon, you will familiar with formula (g) because it faster the (f). 3. 0 SOLUTION TIPS FOR FIRST LAYER. I will not give you the specific formula to solve the first layer ( D ) but the following tips may useful for you. ( We focus on third layer ) 72136066675 3.1Define your base colour; white for example. 72136069215 3.2Match one of edges; lets say green and white 72136081280 3.3 Match the center piece of E (green) with the correct edge ( green-white). That means we lock the E to put the all center pieces of E in correct position. 72136027940448881529845 3.4 Make “PLUS” white of the base. The other side of this cube look like this. 72136040005 3.5Permutate the corner of base (green-red-white). 79756042545 3.6 Permutate all of the corners to put them in exact positions. 4. 0 SIMPLE SOLUTION TIPS OF SECOND LAYER. The following tips may useful for you to solve the second layer; 1. Red face as F ( Front ) 2. Green face as F ( Front ) In this stage, I suggest you to use ( DE ) and ( D’E’ ) instead of F and F’ ,[object Object],Notes : If you are confusing on my diagram, please refer to ( 1.0 ) above. 5.0 SOLVING THIRD LAYER After completing second layer you may get various thirds layer patterns.

Sometimes you will get; ( Make Green face as F , always facing you ) ( A ) ( B ) or Target To make, Concept & Cube PositionBased on illustration above, you must use the Green face as F, surface that always facing you instead of red face.Formula L’ U R U’ L UU R’ U R UU R’ PermutationFor (A ) you will use the formula twice, butFor (B) you just use the formula once.NotesAnd at this stage, you may solve the Rubik cube.
