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 4x4x4 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 4x4x4, there are parity issues which 3x3x3 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 4x4x4, you need to know how to solve a 3x3x3. Now, anyone wants to loan me a 5x5x5?
Tips: Here is a good website for solution http://pjgat09.gotdns.com/old/cube4java.html
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 3x3x3 to solve a 4x4x4, but you do need to know it to solve a 5x5x5 because it’s the same theory. The 4x4x4 uses slightly different moves to correct those parity problems.
I keep my 4x4x4 and 5x5x5 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 3x3x3 everyday, helps pass the time on the bus. Especially with the 1 minute solving times.
