Guess what I am busy with these few days? I got a new toy. Nope it is not the iPhone, in fact I didn’t have time to play with it. My hubby was keying in all his contacts and gets it going.
I got myself a 4×4x4 Rubik’s cube. I was eager to solve it and browsing through the web for solution. If you want to search for the solution, go to YouTube. It has live demo. However I think some of the teachers talk too much.
I managed to solve it within 30 minutes with the first try. Maybe it was beginners luck. Second day, I mixed it up and I started having problems. With the 4×4x4, there are parity issues which 3×3x3 doesn’t. Anyway, formulas must be used for those parity issues. It takes more practice for me to remember those.
In order to solve a 4×4x4, you need to know how to solve a 3×3x3. Now, anyone wants to loan me a 5×5x5?

i didnt touch this cube for more than 10 years already. you keng eh…30mins only!!!
You don’t need to know how to solve a 3×3x3 to solve a 4×4x4, but you do need to know it to solve a 5×5x5 because it’s the same theory. The 4×4x4 uses slightly different moves to correct those parity problems.
I keep my 4×4x4 and 5×5x5 at home though because it’s a little too fragile to play with it on a constant basis. So I play with my sudoku cube and my 3×3x3 everyday, helps pass the time on the bus. Especially with the 1 minute solving times.
